Applied into the ext4 tree after verifying that e2fsck already handles
this case:
% e2fsck -fy /tmp/foo.img
e2fsck 1.44.1 (24-Mar-2018)
Pass 1: Checking inodes, blocks, and sizes
Special (device/socket/fifo/symlink) file (inode 13) has immutable
or append-only flag set. Clear? yes
(The btrfs and xfs maintainers might want to make a similar check
before accepting their respective patches.)
