Bulkstat also checks for ENOENT returns from xfs_iget() as the lookup it does is inherently racy. That is, if the inode is allocated when it is read from the IBT, but then has been unlinked before the actual xfs_iget() call, it expects to get back an ENOENT to tell it the inode has been unlinked and shouldn't be included in the bulkstat output. Otherwise, it returns the error to userspace. So converting the mode checks to return ESTALE definitely has the chance of breaking stuff that uses bulkstat (e.g. xfsdump) because it will return errors now where it previously just skipped the (unlinked) inode.
