  "message": "xfs: remove i_iolock and use i_rwsem in the VFS inode instead\n\nThis patch drops the XFS-own i_iolock and uses the VFS i_rwsem which\nrecently replaced i_mutex instead.  This means we only have to take\none lock instead of two in many fast path operations, and we can\nalso shrink the xfs_inode structure.  Thanks to the xfs_ilock family\nthere is very little churn, the only thing of note is that we need\nto switch to use the lock_two_directory helper for taking the i_rwsem\non two inodes in a few places to make sure our lock order matches\nthe one used in the VFS.\n\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\nTested-by: Jens Axboe \u003caxboe@fb.com\u003e\nReviewed-by: Darrick J.
