Given we don't yet support any feature flags in the dm-raid ondisk metadata (see: 'features' member of 'struct dm_raid_superblock'), add a check to ensure no flags are actually set, if any features are set reject the activation of the RAID mapping. This is to prevent possible data corruption in case of a kernel downgrade when there'll potentially be feature flags set by a future dm-raid target. Signed-off-by:

The primary motivation of this commit is to improve the scalability of DM multipath on large NUMA systems where m->lock spinlock contention has been proven to be a serious bottleneck on really fast storage. The ability to atomically read a pointer, using lockless_dereference(), is leveraged in this commit. But all pointer writes are still protected by the m->lock spinlock (which is fine since these all now occur in the slow-path). The following functions no longer require the m->lock spinlock in their fast-path: multipath_busy(), __multipath_map(), and do_end_io() And choose_pgpath() is modified to _not_ update m->current_pgpath unless it also switches the path-group. This is done to avoid needing to take the m->lock everytime __multipath_map() calls choose_pgpath(). But m->current_pgpath will be reset if it is failed via fail_path(). Suggested-by:

Needed in order to update the DM thinp code to use the new async __blkdev_issue_discard() interface.
-
Mike Snitzer authored
Commit 326e1dbb ("block: remove management of bi_remaining when restoring original bi_end_io") made bio_inc_remaining() private to bio.c because the only use-case that made sense was confined to the bio_chain() interface. Since that time DM thinp went on to use bio_chain() in its relatively complex implementation of async discard support. That implementation, even when converted over to use the new async __blkdev_issue_discard() interface, depends on deferred completion of the original discard bio -- which is most appropriately implemented using bio_inc_remaining(). DM thinp foolishly duplicated bio_inc_remaining(), local to dm-thin.c as __bio_inc_remaining(), so re-exporting bio_inc_remaining() allows us to put an end to that foolishness. All said, bio_inc_remaining() should really only be used in conjunction with bio_chain(). It isn't intended for generic bio reference counting. Signed-off-by:

Commit 38f25255 ("block: add __blkdev_issue_discard") incorrectly disallowed the early return of -EOPNOTSUPP if the device doesn't support discard (or secure discard). This early return of -EOPNOTSUPP has always been part of blkdev_issue_discard() interface so there isn't a good reason to break that behaviour -- especially when it can be easily reinstated. The nuance of allowing early return of -EOPNOTSUPP vs disallowing late return of -EOPNOTSUPP is: if the overall device never advertised support for discards and one is issued to the device it is beneficial to inform the caller that discards are not supported via -EOPNOTSUPP. But if a device advertises discard support it means that at least a subset of the device does have discard support -- but it could be that discards issued to some regions of a stacked device will not be supported. In that case the late return of -EOPNOTSUPP must be disallowed. Fixes: 38f25255 ("block: add __blkdev_issue_discard") Signed-off-by:

Both of these drivers can return NOTIFY_BAD, but this terminates processing other callbacks that were registered later on the chain. Since the driver did nothing to log the error it seems wrong to prevent other interested parties from seeing it. E.g. neither of them had even bothered to check the type of the error to see if it was a memory error before the return NOTIFY_BAD. Signed-off-by:
