Brian Behlendorf 7973e464de Revert "Revert "Fix unlink/xattr deadlock"" ... This reverts commit 53c7411919 effectively reinstating the asynchronous xattr cleanup code. These Linux changes were reverted because after testing and careful contemplation I was convinced that due to the 89260a1c8851ce05ea04b23606ba438b271d890 commit they were no longer required. Unfortunately, the deadlock described in #1176 was a case which wasn't considered. At mount zfs_unlinked_drain() can occur which will unlink a list of znodes in effectively a random order which isn't safe. The only reason it was safe to originally revert this change was the we could guarantee that the VFS would always prune the xattr leaves before the parents. Therefore, until we can cleanly resolve this deadlock for all cases we need to keep this change in spite of the xattr unlink performance penalty associated with it.
