We are seeing a large regression in database performance on recent kernels. The database opens a block device with O_DIRECT|O_SYNC and a number of threads write to different regions of the file at the same time. A simple test case is below. I haven't defined DEVICE since getting it wrong will destroy your data :) On an 3 disk LVM with a 64k chunk size we see about 17MB/sec and only a few threads in IO wait: procs -----io---- -system-- -----cpu------ r b bi bo in cs us sy id wa st 0 3 0 16170 656 2259 0 0 86 14 0 0 2 0 16704 695 2408 0 0 92 8 0 0 2 0 17308 744 2653 0 0 86 14 0 0 2 0 17933 759 2777 0 0 89 10 0 Most threads are blocking in vfs_fsync_range, which has: mutex_lock(&mapping->host->i_mutex); err = fop->fsync(file, dentry, datasync); if (!ret) ret = err; mutex_unlock(&mapping->host->i_mutex); commit 148f948b (vfs: Introduce new helpers for syncing after writing to O_SYNC file or IS_SYNC inode) offers some explanation of what is going on: Use these new helpers for syncing from generic VFS functions. This makes O_SYNC writes to block devices acquire i_mutex for syncing. If we really care about this, we can make block_fsync() drop the i_mutex and reacquire it before it returns. Thanks Jan for such a good commit message! As well as dropping i_mutex, Christoph suggests we should remove the call to sync_blockdev(): > sync_blockdev is an overcomplicated alias for filemap_write_and_wait on > the block device inode, which is exactly what we did just before calling > into ->fsync The patch below incorporates both suggestions. With it the testcase improves from 17MB/s to 68M/sec: procs -----io---- -system-- -----cpu------ r b bi bo in cs us sy id wa st 0 7 0 65536 1000 3878 0 0 70 30 0 0 34 0 69632 1016 3921 0 1 46 53 0 0 57 0 69632 1000 3921 0 0 55 45 0 0 53 0 69640 754 4111 0 0 81 19 0 Testcase: #define _GNU_SOURCE #include <stdio.h> #include <pthread.h> #include <unistd.h> #include <stdlib.h> #include <string.h> #include <sys/types.h> #include <sys/stat.h> #include <fcntl.h> #define NR_THREADS 64 #define BUFSIZE (64 * 1024) #define DEVICE "/dev/mapper/XXXXXX" #define ALIGN(VAL, SIZE) (((VAL)+(SIZE)-1) & ~((SIZE)-1)) static int fd; static void *doit(void *arg) { unsigned long offset = (long)arg; char *b, *buf; b = malloc(BUFSIZE + 1024); buf = (char *)ALIGN((unsigned long)b, 1024); memset(buf, 0, BUFSIZE); while (1) pwrite(fd, buf, BUFSIZE, offset); } int main(int argc, char *argv[]) { int flags = O_RDWR|O_DIRECT; int i; unsigned long offset = 0; if (argc > 1 && !strcmp(argv[1], "O_SYNC")) flags |= O_SYNC; fd = open(DEVICE, flags); if (fd == -1) { perror("open"); exit(1); } for (i = 0; i < NR_THREADS-1; i++) { pthread_t tid; pthread_create(&tid, NULL, doit, (void *)offset); offset += BUFSIZE; } doit((void *)offset); return 0; } Signed-off-by:Anton Blanchard <anton@samba.org> Acked-by:

This patch fixes 2 issues with the LZO decompressor: - It doesn't handle the case where a block isn't compressed at all. In this case, calling lzo1x_decompress_safe will fail, so we need to just use memcpy() instead (the upstream LZO code does something similar) - Since commit 54291362 ("initramfs: add missing decompressor error check") , the decompressor return code is checked in the init/initramfs.c The LZO decompressor didn't return the expected value, causing the initramfs code to falsely believe a decompression error occured Signed-off-by:

If a futex key happens to be located within a huge page mapped MAP_PRIVATE, get_futex_key() can go into an infinite loop waiting for a page->mapping that will never exist. See https://bugzilla.redhat.com/show_bug.cgi?id=552257 for more details about the problem. This patch makes page->mapping a poisoned value that includes PAGE_MAPPING_ANON mapped MAP_PRIVATE. This is enough for futex to continue but because of PAGE_MAPPING_ANON, the poisoned value is not dereferenced or used by futex. No other part of the VM should be dereferencing the page->mapping of a hugetlbfs page as its page cache is not on the LRU. This patch fixes the problem with the test case described in the bugzilla.

Description of patch: --------------------- This is a patch for the EFI framebuffer driver to enable the framebuffer of the NVIDIA 9400M as found in MacBook Pro (MBP) 5,1 and up. The framebuffer of the NVIDIA graphic cards are located at the following addresses in memory: 9400M: 0xC0010000 9600M GT: 0xB0030000 The patch delivered right here only provides the memory location of the framebuffer of the 9400M device. The 9600M GT is not covered. It is assumed that the 9400M is used when powered up the MBP. The information which device is currently powered and in use is stored in the 64 bytes large EFI variable "gpu-power-prefs". More specifically, byte 0x3B indicates whether 9600M GT (0x00) or 9400M (0x01) is online. The PCI bus IDs are the following: 9400M: PCI 03:00:00 9600M GT: PCI 02:00:00 The EFI variables can be easily read-out and manipulated with "rEFIt", an MBP specific bootloader tool. For more information on how handle rEFIt and EFI variables please consult "http://refit.sourceforge.net" and "http://ubuntuforums.org/archive/index.php/t-1076879.html". IMPORTANT NOTE: The information on how to activate the 9400M device given at "ubuntuforums.org" is not correct, since it states gpu-power-prefs[0x3B] = 0x00 -> 9400M (PCI 02:00:00) gpu-power-prefs[0x3B] = 0x01 -> 9600M GT (PCI 03:00:00) Actually, the assignment of the values and the PCI bus IDs are swapped. Suggestions: ------------ To cover framebuffers of both 9400M and 9600M GT, I would suggest to implement a conditional on "gpu-power-prefs". Depending on the value of byte 0x3B, the according framebuffer is selected. However, this requires kernel access to the EFI variables.

We must tell GCC to use even register for variable passed to ldrd instruction. Without this patch GCC 4.2.1 puts this variable to r2/r3 on EABI and r3/r4 on OABI, so force it to r2/r3.

Commit 48b32a35 ("reiserfs: use generic xattr handlers") introduced a problem that causes corruption when extended attributes are replaced with a smaller value. The issue is that the reiserfs_setattr to shrink the xattr file was moved from before the write to after the write. The root issue has always been in the reiserfs xattr code, but was papered over by the fact that in the shrink case, the file would just be expanded again while the xattr was written. The end result is that the last 8 bytes of xattr data are lost. This patch fixes it to use new_size. Addresses https://bugzilla.kernel.org/show_bug.cgi?id=14826Signed-off-by:

Commit 677c9b2e ("reiserfs: remove privroot hiding in lookup") removed the magic from the lookup code to hide the .reiserfs_priv directory since it was getting loaded at mount-time instead. The intent was that the entry would be hidden from the user via a poisoned d_compare, but this was faulty. This introduced a security issue where unprivileged users could access and modify extended attributes or ACLs belonging to other users, including root. This patch resolves the issue by properly hiding .reiserfs_priv. This was the intent of the xattr poisoning code, but it appears to have never worked as expected. This is fixed by using d_revalidate instead of d_compare. This patch makes -oexpose_privroot a no-op. I'm fine leaving it this way. The effort involved in working out the corner cases wrt permissions and caching outweigh the benefit of the feature. Signed-off-by:

This cleans up a few of the complaints of __generic_block_fiemap. I've fixed all the typing stuff, used inline functions instead of macros, gotten rid of a couple of variables, and made sure the size and block requests are all block aligned. It also fixes a problem where sometimes FIEMAP_EXTENT_LAST wasn't being set properly. Signed-off-by:

My PIPE_CONTROL fix (just sent via Eric's tree) was buggy; I was testing a whole set of patches together and missed a conversion to the new HAS_PIPE_CONTROL macro, which will cause breakage on non-Ironlake 965 class chips. Fortunately, the fix is trivial and has been tested. Be sure to use the HAS_PIPE_CONTROL macro in i915_get_gem_seqno, or we'll end up reading the wrong graphics memory, likely causing hangs, crashes, or worse. Reported-by:

It is a hard requirement to include the upstream commit ID in the changelog of a -stable submission, not just a courtesy to the stable team. This concerns only mail submission though, which is no longer the only way into stable. (Also, fix a double "the".) Signed-off-by:

It seems that for USB IP on Freescale MX5x processors, it needs >750 usec for the reset to complete. This change should not hurt any other EHCI hardware. Signed-off-by:

This patch (as1370) fixes a bug in the USB runtime power management code. When a driver claims an interface, it doesn't expect to need to call usb_autopm_get_interface() or usb_autopm_put_interface() for runtime PM to work. Runtime PM can be controlled by the driver's primary interface; the additional interfaces it claims shouldn't interfere. As things stand, the claimed interfaces will prevent the device from autosuspending. To fix this problem, the patch sets interfaces to the suspended state when they are claimed. Also, although in theory this shouldn't matter, the patch changes the suspend code so that interfaces are suspended in reverse order from detection and resuming. This is how the PM core works, and we ought to use the same approach. Signed-off-by:

This patch (as1369) fixes a problem in ehci-hcd. Some controllers occasionally run into trouble when the driver reclaims siTDs too quickly. This can happen while streaming audio; it causes the controller to crash. The patch changes siTD reclamation to work the same way as iTD reclamation: Completed siTDs are stored on a list and not reused until at least one frame has passed. Signed-off-by:

This patch (as1363) changes the way USB remote wakeup is handled during system sleeps. It won't be enabled unless an interface driver specifically needs it. Also, it won't be enabled during the FREEZE or QUIESCE phases of hibernation, when the system doesn't respond to wakeup events anyway. Finally, if the device is already runtime-suspended with remote wakeup enabled, but wakeup is supposed to be disabled for the system sleep, the device gets woken up so that it can be suspended again with the proper wakeup setting. This will fix problems people have reported with certain USB webcams that generate wakeup requests when they shouldn't, and as a result cause system suspends to fail.
