Commit commit 65b8291c ("dio: invalidate clean pages before dio write") introduced a bug which stopped dio from ever invalidating the page cache after writes. It still invalidated it before writes so most users were fine. Karl Schendel reported ( http://lkml.org/lkml/2007/10/26/481 ) hitting this bug when he had a buffered reader immediately reading file data after an O_DIRECT wirter had written the data. The kernel issued read-ahead beyond the position of the reader which overlapped with the O_DIRECT writer. The failure to invalidate after writes caused the reader to see stale data from the read-ahead. The following patch is originally from Karl. The following commentary is his: The below 3rd try takes on your suggestion of just invalidating no matter what the retval from the direct_IO call. I ran it thru the test-case several times and it has worked every time. The post-invalidate is probably still too early for async-directio, but I don't have a testcase for that; just sync. And, this won't be any worse in the async case. I added a test to the aio-dio-regress repository which mimics Karl's IO pattern. It verifed the bad behaviour and that the patch fixed it. I agree with Karl, this still doesn't help the case where a buffered reader follows an AIO O_DIRECT writer. That will require a bit more work. This gives up on the idea of returning EIO to indicate to userspace that stale data remains if the invalidation failed. Signed-off-by:

It's currently possible to send posix_locks_deadlock() into an infinite loop (under the BKL). For now, fix this just by bailing out after a few iterations. We may want to fix this in a way that better clarifies the semantics of deadlock detection. But that will take more time, and this minimal fix is probably adequate for any realistic scenario, and is simple enough to be appropriate for applying to stable kernels now.

Evgeniy said: I wonder on what type of UFS do you test this patch? NetBSD and FreeBSD do not use "fs_state", they use "fs_clean" flag, only Solaris does check like this: fs_state + fs_time == FSOK. That's why parentheses was like that. At now with linux-2.6.24-rc1-git1, I get: fs need fsck, but NetBSD's fsck says that's all ok. I suggest revert this patch.

It's possible to provoke unionfs (not yet in mainline, though in mm and some distros) to hit shmem_writepage's BUG_ON(page_mapped(page)). I expect it's possible to provoke the 2.6.23 ecryptfs in the same way (but the 2.6.24 ecryptfs no longer calls lower level's ->writepage). This came to light with the recent find that AOP_WRITEPAGE_ACTIVATE could leak from tmpfs via write_cache_pages and unionfs to userspace. There's already a fix (e4230030 - writeback: don't propagate AOP_WRITEPAGE_ACTIVATE) in the tree for that, and it's okay so far as it goes; but insufficient because it doesn't address the underlying issue, that shmem_writepage expects to be called only by vmscan (relying on backing_dev_info capabilities to prevent the normal writeback path from ever approaching it). That's an increasingly fragile assumption, and ramdisk_writepage (the other source of AOP_WRITEPAGE_ACTIVATEs) is already careful to check wbc->for_reclaim before returning it. Make the same check in shmem_writepage, thereby sidestepping the page_mapped BUG also. Signed-off-by:

mm/sparse-vmemmap.c uses init_mm in some places. However, it is not present in any of the headers currently included in the file. init_mm is defined as extern in sched.h, so we add it to the headers list Up to now, this problem was masked by the fact that functions like set_pte_at() and pmd_populate_kernel() are usually macros that expand to simpler variants that does not use the first parameter at all.

Implement ATA_QCFLAG_QUIET which indicates that there's no need to report if the command fails with AC_ERR_DEV and set it for passthrough commands. Combined with previous changes, this now makes device errors for all direct commands reported directly to the issuer without going through EH actions and reporting. Note that EH is still invoked after non-IO device errors to determine the nature of the error and resume command execution (some controller requires special care after error to continue). It just performs default maintenance after error, examines what's going on, realizes that it's none of its business and reports the command failure without logging any error messages. Signed-off-by:

libata EH always revalidated device and retried failed command after error except for ATAPI CCs. This is unnecessary and hinders with users issuing direct commands. This patch makes the following changes. * Make sata_sil24 not request ATA_EH_REVALIDATE on device errors. sil24 is the only driver which does this. All others let libata EH core code decide. * Don't request revalidation after device error of non-IO command. Revalidation doesn't really help anybody. As ATA_EH_REVALIDATE isn't set by default, there's no reason to clear it after sense data is read. Kill ATA_EH_REVALIDATE clearing code while at it. * Don't retry non-IO command after device error. Device has rejected the command. There's no point in retrying. Signed-off-by:

Second-generation Promise SATA controllers have an ASIC bug which can trigger if the last PRD entry is larger than 164 bytes, resulting in intermittent errors and possible data corruption. Work around this by replacing calls to ata_qc_prep() with a private version that fills the PRD, checks the size of the last entry, and if necessary splits it to avoid the bug. Also reduce sg_tablesize by 1 to accommodate the new entry. Tested on the second-generation SATA300 TX4 and SATA300 TX2plus, and the first-generation PDC20378. Thanks to Alexander Sabourenkov for verifying the bug by studying the vendor driver, and for writing the initial patch upon which this one is based. Signed-off-by:
