If ext3 filesystem is larger than 2TB, and sector_t is a u32 (i.e. CONFIG_LBD not defined in the kernel), the calculation of the disk sector will overflow. Add check at ext3_fill_super() and ext3_group_extend() to prevent mount/remount/resize >2TB ext3 filesystem if sector_t size is 4 bytes. Verified this patch on a 32 bit platform without CONFIG_LBD defined (sector_t is 32 bits long), mount refuse to mount a 10TB ext3. Signed-off-by: Mingming Cao<cmm@us.ibm.com> Acked-by:

schedule_on_each_cpu() presently does a large kmalloc - 96 kbytes on 1024 CPU 64-bit. Rework it so that we do one 8192-byte allocation and then a pile of tiny ones, via alloc_percpu(). This has a much higher chance of success (100% in the current VM). This also has the effect of reducing the memory requirements from NR_CPUS*n to num_possible_cpus()*n.

Drop leading space of kernel-doc section contents. "Section" data (contents) are split from the section header (e.g., Note: below is a section header: * Note: list_empty on entry does not return true after this, the entry is * in an undefined state. ). Currently the data/contents begins with a space and is left that way, which causes it to look bad when printed (in text mode; see example below), so just remove the leading space. Note: list_empty on entry does not return true after this, the entry is in an undefined state. Signed-off-by:

pdflush is carefully designed to ensure that all wakeups have some corresponding work to do - if a woken-up pdflush thread discovers that it hasn't been given any work to do then this is considered an error. That all broke when swsusp came along - because a timer-delivered wakeup to a frozen pdflush thread will just get lost. This causes the pdflush thread to get lost as well: the writeback timer is supposed to be re-armed by pdflush in process context, but pdflush doesn't execute the callout which does this. Fix that up by ignoring the return value from try_to_freeze(): jsut proceed, see if we have any work pending and only go back to sleep if that is not the case. Signed-off-by:

This is a patch from Alan that fixes a real ide-cd.c regression causing bogus "Media Check" failures for perfectly valid Fedora install ISOs, on certain CD-ROM drives. This is a forward port to 2.6.16 (from RHEL) of the minimal changes for the end of media problem. It may not be sufficient for some controllers (promise notably) and it does not touch the locking so the error path locking is as horked as in mainstream. From: Ingo Molnar <mingo@elte.hu> I have ported the patch to 2.6.17-rc4 and tested it by provoking end-of-media IO errors with an unaligned ISO image. Unlike the vanilla kernel, the patched kernel interpreted the error condition correctly with 512 byte granularity: hdc: command error: status=0x51 { DriveReady SeekComplete Error } hdc: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 } ide: failed opcode was: unknown ATAPI device hdc: Error: Illegal request -- (Sense key=0x05) Illegal mode for this track or incompatible medium -- (asc=0x64, ascq=0x00) The failed "Read 10" packet command was: "28 00 00 04 fb 78 00 00 06 00 00 00 00 00 00 00 " end_request: I/O error, dev hdc, sector 1306080 Buffer I/O error on device hdc, logical block 163260 Buffer I/O error on device hdc, logical block 163261 Buffer I/O error on device hdc, logical block 163262 the unpatched kernel produces an incorrect error dump: hdc: command error: status=0x51 { DriveReady SeekComplete Error } hdc: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 } ide: failed opcode was: unknown end_request: I/O error, dev hdc, sector 1306080 Buffer I/O error on device hdc, logical block 163260 hdc: command error: status=0x51 { DriveReady SeekComplete Error } hdc: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 } ide: failed opcode was: unknown end_request: I/O error, dev hdc, sector 1306088 Buffer I/O error on device hdc, logical block 163261 hdc: command error: status=0x51 { DriveReady SeekComplete Error } hdc: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 } ide: failed opcode was: unknown end_request: I/O error, dev hdc, sector 1306096 Buffer I/O error on device hdc, logical block 163262 I do not have the right type of CD-ROM drive to reproduce the end-of-media data corruption bug myself, but this same patch in RHEL solved it.

Currently printk is no use for early debugging because it refuses to actually print anything to the console unless cpu_online(smp_processor_id()) is true. The stated explanation is that console drivers may require per-cpu resources, or otherwise barf, because the system is not yet setup correctly. Fair enough. However some console drivers might be quite happy running early during boot, in fact we have one, and so it'd be nice if printk understood that. So I added a flag (which I would have called CON_BOOT, but that's taken) called CON_ANYTIME, which indicates that a console is happy to be called anytime, even if the cpu is not yet online. Tested on a Power 5 machine, with both a CON_ANYTIME driver and a bogus console driver that BUG()s if called while offline. No problems AFAICT. Built for i386 UP & SMP. Signed-off-by:

In both the read and write cases it will return an error if copy_{from/to}_user faults. However, I let the driver try to read/write as much as it can just as it normally would , then finally it returns an error if there was one. This was the most straight forward way to handle the error , since there isn't a clear way to clean up the buffers on error . I moved retval in idetape_chrdev_write() down into the actual code blocks since it's really once used there, and it conflicted with my ret variable.

ufs super block contains some statistic about file systems, like amount of directories, free blocks, inodes and so on. UFS1 hold this information in one location and uses 32bit integers for such information, UFS2 hold statistic in another location and uses 64bit integers. There is transition variant, if UFS1 has type 44BSD and flags field in super block has some special value this mean that we work with statistic like UFS2 does. and this also means that nobody care about old(UFS1) statistic. So if start fsck against such file system, after usage linux ufs driver, it found error: at now only UFS1 like statistic is updated. This patch should fix this. Also it contains some minor cleanup: CodingSytle and remove unused variables. Signed-off-by:

Super block of UFS usually has size >512, because of fragment size may be 512, this cause some problems. Currently, there are two methods to work with ufs super block: 1) split structure which describes ufs super blocks into structures with size <=512 2) use one structure which describes ufs super block, and hope that array of "buffer_head" which holds "super block", has such construction: bh[n]->b_data + bh[n]->b_size == bh[n + 1]->b_data The second variant may cause some problems in the future, and usage of two variants cause unnecessary code duplication. This patch remove the second variant. Also patch contains some CodingStyle fixes. Signed-off-by:
