[PATCH] Btrfs: check for an extent_op on the locked ref

2014-03-27 Thread Josef Bacik
We could have possibly added an extent_op to the locked_ref while we dropped locked_ref-lock, so check for this case as well and loop around. Otherwise we could lose flag updates which would lead to extent tree corruption. Thanks, cc: stable@vger.kernel.org Signed-off-by: Josef Bacik

[PATCH] [media] uvcvideo: Fix clock param realtime setting
