Darrick J. Wong 27e46e4c63 xfs: fix an ABBA deadlock in xfs_rename ... When overlayfs is running on top of xfs and the user unlinks a file in the overlay, overlayfs will create a whiteout inode and ask xfs to "rename" the whiteout file atop the one being unlinked. If the file being unlinked loses its one nlink, we then have to put the inode on the unlinked list. This requires us to grab the AGI buffer of the whiteout inode to take it off the unlinked list (which is where whiteouts are created) and to grab the AGI buffer of the file being deleted. If the whiteout was created in a higher numbered AG than the file being deleted, we'll lock the AGIs in the wrong order and deadlock. Therefore, grab all the AGI locks we think we'll need ahead of time, and in order of increasing AG number per the locking rules.
