And now the subject line for the patch is far too long. it is almost twice as long as the old one, doesn't fit on one line without wrapping, and really doesn't tell us anything much extra. If you really must say it's a whiteout issue, then: xfs: Fix deadlock between AGI and AGF with RENAME_WHITEOUT is sufficient. It's a summary - the above contains the problem, the objects involved and the operation that needs to be fixed. Nothing more is necessary. It needs to fit into ~60 characters so that when you run git log --one-line the output can be pasted directly into email without wrapping.... Cheers, Dave. -- Dave Chinner david@xxxxxxxxxxxxx
