xfs: evict all inodes involved with log redo item
commit 799ea9e9c59949008770aab4e1da87f10e99dbe4 upstream. When we introduced the bmap redo log items, we set MS_ACTIVE on the mountpoint and XFS_IRECOVERY on the inode to prevent unlinked inodes from being truncated prematurely during log recovery. This also had the effect of putting linked inodes on the lru instead of evicting them. Unfortunately, we neglected to find all those unreferenced lru inodes and evict them after finishing log recovery, which means that we leak them if anything goes wrong in the rest of xfs_mountfs, because the lru is only cleaned out on unmount. Therefore, evict unreferenced inodes in the lru list immediately after clearing MS_ACTIVE. Fixes: 17c12bcd30 ("xfs: when replaying bmap operations, don't let unlinked inodes get reaped") Signed-off-by: Darrick J.
