xfs: refactor inode ownership change transaction/inode/quota allocation idiom
For file ownership (uid, gid, prid) changes, create a new helper xfs_trans_alloc_ichange that allocates a transaction and reserves the appropriate amount of quota against that transction in preparation for a change of user, group, or project id. Replace all the open-coded idioms with a single call to this helper so that we can contain the retry loops in the next patchset. This changes the locking behavior for ichange transactions slightly. Since tr_ichange does not have a permanent reservation and cannot roll, we pass XFS_ILOCK_EXCL to ijoin so that the inode will be unlocked automatically at commit time. Signed-off-by: Darrick J.
