drm/i915/dp: add native aux defer retry limit

2014-03-05T16:13:57+00:00

commit f51a44b9a6c4982cc25bfb3727de9bb893621ebc upstream.

Retrying indefinitely places too much trust on the aux implementation of
the sink devices.

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

2014-03-05T16:13:57+00:00

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

2014-03-05T16:13:55+00:00

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.

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

2014-03-05T16:13:55+00:00

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().
