drm/i915/dp: increase native aux defer retry timeout

2014-03-05T16:13:57Z

commit 04eada25d1f72efdecd32d702706594f81de65d5 upstream. Give more slack to sink devices before retrying on native aux defer. AFAICT the 100 us timeout was not based on the DP spec.

dm thin: fix the error path for the thin device constructor

2014-03-05T16:13:55Z

commit 1acacc0784aab45627b6009e0e9224886279ac0b upstream. dm_pool_close_thin_device() must be called if dm_set_target_max_io_len() fails in thin_ctr(). Otherwise __pool_destroy() will fail because the pool will still have an open thin device: device-mapper: thin metadata: attempt to close pmd when 1 device(s) are still open device-mapper: thin: __pool_destroy: dm_pool_metadata_close() failed. Also, must establish error code if failing thin_ctr() because the pool is in fail_io mode. Signed-off-by: Mike Snitzer Acked-by: Joe Thornber Signed-off-by: Jiri Slaby

dm thin: avoid metadata commit if a pool's thin devices haven't changed

2014-03-05T16:13:55Z

commit 4d1662a30dde6e545086fe0e8fd7e474c4e0b639 upstream. Commit 905e51b ("dm thin: commit outstanding data every second") introduced a periodic commit. This commit occurs regardless of whether any thin devices have made changes. Fix the periodic commit to check if any of a pool's thin devices have changed using dm_pool_changed_this_transaction().

dm mpath: fix stalls when handling invalid ioctls

2014-03-05T16:13:55Z

commit a1989b330093578ea5470bea0a00f940c444c466 upstream. An invalid ioctl will never be valid, irrespective of whether multipath has active paths or not. So for invalid ioctls we do not have to wait for multipath to activate any paths, but can rather return an error code immediately. This fix resolves numerous instances of: udevd[]: worker [] unexpectedly returned with status 0x0100 that have been seen during testing.
