There are several places where we use KM_SLEEP allocation contexts and use the fact that they are called from transaction context to add KM_NOFS where appropriate. Unfortunately, there are several places where the code makes this assumption but can be called from outside transaction context but with filesystem locks held. These places need explicit KM_NOFS annotations to avoid lockdep complaining about reclaim contexts. Signed-off-by:

The offset passed into xfs_free_file_space() needs to be rounded down to a certain size, but the rounding mask is built by a 32 bit variable. Hence the mask will always mask off the upper 32 bits of the offset and lead to incorrect writeback and invalidation ranges. This is not actually exposed as a bug because we writeback and invalidate from the rounded offset to the end of the file, and hence the offset we are actually punching a hole out of will always be covered by the code. This needs fixing, however, if we ever want to use exact ranges for writeback/invalidation here... Signed-off-by:

FSX on 512 byte block size filesystems has been failing for some time with corrupted data. The fault dates back to the change in the writeback data integrity algorithm that uses a mark-and-sweep approach to avoid data writeback livelocks. Unfortunately, a side effect of this mark-and-sweep approach is that each page will only be written once for a data integrity sync, and there is a condition in writeback in XFS where a page may require two writeback attempts to be fully written. As a result of the high level change, we now only get a partial page writeback during the integrity sync because the first pass through writeback clears the mark left on the page index to tell writeback that the page needs writeback.... The cause is writing a partial page in the clustering code. This can happen when a mapping boundary falls in the middle of a page - we end up writing back the first part of the page that the mapping covers, but then never revisit the page to have the remainder mapped and written. The fix is simple - if the mapping boundary falls inside a page, then simple abort clustering without touching the page. This means that the next ->writepage entry that write_cache_pages() will make is the page we aborted on, and xfs_vm_writepage() will map all sections of the page correctly. This behaviour is also optimal for non-data integrity writes, as it results in contiguous sequential writeback of the file rather than missing small holes and having to write them a "random" writes in a future pass. With this fix, all the fsx tests in xfstests now pass on a 512 byte block size filesystem on a 4k page machine. Signed-off-by:

Writing a large file using direct IO in 16 MB chunks sometimes results in a pathological allocation pattern where 16 MB chunks of large free extent are allocated to a file in a reversed order. So extents of a file look for example as: ext logical physical expected length flags 0 0 13 4550656 1 4550656 188136807 4550668 12562432 2 17113088 200699240 200699238 622592 3 17735680 182046055 201321831 4096 4 17739776 182041959 182050150 4096 5 17743872 182037863 182046054 4096 6 17747968 182033767 182041958 4096 7 17752064 182029671 182037862 4096 ... 6757 45400064 154381644 154389835 4096 6758 45404160 154377548 154385739 4096 6759 45408256 252951571 154381643 73728 eof This happens because XFS_ALLOCTYPE_THIS_BNO allocation fails (the last extent in the file cannot be further extended) so we fall back to XFS_ALLOCTYPE_NEAR_BNO allocation which picks end of a large free extent as the best place to continue the file. Since the chunk at the end of the free extent again cannot be further extended, this behavior repeats until the whole free extent is consumed in a reversed order. For data allocations this backward allocation isn't beneficial so make xfs_alloc_compute_diff() pick start of a free extent instead of its end for them. That avoids the backward allocation pattern. See thread at http://oss.sgi.com/archives/xfs/2013-03/msg00144.html for more details about the reproduction case and why this solution was chosen. Based on idea by Dave Chinner <dchinner@redhat.com>.

While MIPS has announced hardware virtualization extensions this KVM extension uses trap and emulate mode for virtualization of MIPS32.

These enums have been separate since the dawn of SAS, mainly because the latter is a procotol only enum and the former includes additional state for libsas.

The one kept is effectively the sas.h one, but call it sas_device_type and make sure the enums are all properly namespaced with the SAS_ prefix. Signed-off-by:

scsi_send_eh_cmnd() is calling queuecommand() directly, so it needs to check the return value here. The only valid return codes for queuecommand() are 'busy' states, so we need to wait for a bit to allow the LLDD to recover. Based on an earlier patch from Wen Xiong.
