Paul Dagnelie 2921ad6cba Fix zrele race in zrele_async that can cause hang ... There is a race condition in zfs_zrele_async when we are checking if we would be the one to evict an inode. This can lead to a txg sync deadlock. Instead of calling into iput directly, we attempt to perform the atomic decrement ourselves, unless that would set the i_count value to zero. In that case, we dispatch a call to iput to run later, to prevent a deadlock from occurring.
