Analyze and fix the following issue in the Linux kernel code: xfs: xfs_iget in the directory scrubber needs to use UNTRUSTED
Problem Details: In commit 4b80ac64450f, we tried to strengthen the directory scrubber by using the iget call to detect directory entries that point to unallocated inodes. Unfortunately, that commit neglected to pass XFS_IGET_UNTRUSTED to xfs_iget, so we don't check the inode btree first. If the inode number points to...
