Subject[PATCH v1 0/7] Minor Raid5 Fixes and Cleanup
Hi,

This series contains a few cleanup and minor fixes to the raid5 code
to make it a bit easier to hack on.

Patch 1 cleans up the error returns in setup_conf() (I had an
abandonded patch that added another error out and needed this clean
more sensible).

Patch 2 fixes a sparse warning with the raid5_percpu structure.

Patch 3 through 6 fixes sparse warnings related to missing __rcu
annotations when using the RCU calls.

Patch 7 just adds some basic __must_hold annotations for the device_lock
to any function that is called while holding the lock. Sparse doesn't
really check this, but the annotation makes the locks a little easier
to analyze.

Thanks,

Logan
