Move sys_mmap_pgoff() from mm/util.c to mm/mmap.c and mm/nommu.c, where we'd expect to find such code: especially now that it contains the MAP_HUGETLB handling. Revert mm/util.c to how it was in 2.6.32. This patch just ignores MAP_HUGETLB in the nommu case, as in 2.6.32, whereas 2.6.33-rc2 reported -ENOSYS. Perhaps validate_mmap_request() should reject it with -EINVAL? Add that later if necessary.

commit 45465487 ("kfifo: move struct kfifo in place") caused a compile failure in ibmvscsitgt.c because it changed a pointer to kfifo in the libsrp.h structure to a direct inclusion without including <linux/kfifo.h>. The fix is simple, just add the include, but how did this happen? This change, introduced at -rc2, hardly looks like a bug fix, and it clearly didn't go through linux-next, which would have picked up this compile failure (it only occurs on ppc because of the ibm virtual scsi target).

由 Theodore Ts'o 提交于
As reported in Kernel Bugzilla #14936, commit d21cd8f1 triggered a BUG in the function ext4_da_update_reserve_space() found in fs/ext4/inode.c. The root cause of this BUG() was caused by the fact that ext4_calc_metadata_amount() can severely over-estimate how many metadata blocks will be needed, especially when using direct block-mapped files. In addition, it can also badly *under* estimate how much space is needed, since ext4_calc_metadata_amount() assumes that the blocks are contiguous, and this is not always true. If the application is writing blocks to a sparse file, the number of metadata blocks necessary can be severly underestimated by the functions ext4_da_reserve_space(), ext4_da_update_reserve_space() and ext4_da_release_space(). This was the cause of the dq_claim_space reports found on kerneloops.org. Unfortunately, doing this right means that we need to massively over-estimate the amount of free space needed. So in some cases we may need to force the inode to be written to disk asynchronously in to avoid spurious quota failures. http://bugzilla.kernel.org/show_bug.cgi?id=14936Signed-off-by: N"Theodore Ts'o" <tytso@mit.edu>

If two arrays share a device, then they will not both resync at the same time. One will wait for the other to complete. While waiting, the MD_RECOVERY_INTR flag is not checked so a device failure, which would make the resync pointless, does not cause the resync to abort, so the failed device cannot be removed (as it cannot be remove while a resync is happening). So add a test for MD_RECOVERY_INTR. Reported-by: NBrett Russ <bruss@netezza.com> Signed-off-by: NNeilBrown <neilb@suse.de>

Since commit dfc70645, ->hot_remove_disks has not removed non-failed devices from an array until recovery is no longer possible. So the code in do_md_run to get around the fact that md_check_recovery (which calls ->hot_remove_disks) would remove partially-in-sync devices is no longer needed. So remove it.

The start_ro modules parameter can be used to force arrays to be started in 'auto-readonly' in which they are read-only until the first write. This ensures that no resync/recovery happens until something else writes to the device. This is important for resume-from-disk off an md array. However if an array is started 'readonly' (by writing 'readonly' to the 'array_state' sysfs attribute) we want it to be really 'readonly', not 'auto-readonly'. So strengthen the condition to only set auto-readonly if the array is not already read-only. Signed-off-by: NNeilBrown <neilb@suse.de>

evms configures md arrays by: open device send ioctl close device for each different ioctl needed. Since 2.6.29, the device can disappear after the 'close' unless a significant configuration has happened to the device. The change made by "SET_ARRAY_INFO" can too minor to stop the device from disappearing, but important enough that losing the change is bad. So: make sure SET_ARRAY_INFO sets mddev->ctime, and keep the device active as long as ctime is non-zero (it gets zeroed with lots of other things when the array is stopped). This is suitable for -stable kernels since 2.6.29. Signed-off-by: NNeilBrown <neilb@suse.de> Cc: stable@kernel.org

由 Luis R. Rodriguez 提交于
mac80211 does not propagate failed hardware reconfiguration requests. For suspend and resume this is important due to all the possible issues that can come out of the suspend <-> resume cycle. Not propagating the error means cfg80211 will assume the resume for the device went through fine and mac80211 will continue on trying to poke at the hardware, enable timers, queue work, and so on for a device which is completley unfunctional. The least we can do is to propagate device start issues and warn when this occurs upon resume. A side effect of this patch is we also now propagate the start errors upon harware reconfigurations (non-suspend), but this should also be desirable anyway, there is not point in continuing to reconfigure a device if mac80211 was unable to start the device.

由 Luis R. Rodriguez 提交于
When mac80211 suspends it calls a driver's suspend callback as a last step and after that the driver assumes no calls will be made to it until we resume and its start callback is kicked. If such calls are made, however, suspend can end up throwing hardware in an unexpected state and making the device unusable upon resume. Fix this by preventing mac80211 to schedule dynamic_ps_disable_work by checking for when mac80211 starts to suspend and starts quiescing. Frames should be allowed to go through though as that is part of the quiescing steps and we do not flush the mac80211 workqueue since it was already done towards the beginning of suspend cycle. The other mac80211 issue will be hanled in the next patch. For further details see refer to the thread: http://marc.info/?t=126144866100001&r=1&w=2 Cc: stable@kernel.org Signed-off-by: NLuis R.
