ext2: fix a block leak commit 5aa1437d2d9a068c0334bd7c9dafa8ec4f97f13b upstream. open file, unlink it, then use ioctl(2) to make it immutable or append only. Now close it and watch the blocks *not* freed... Immutable/append-only checks belong in ->setattr(). Note: the bug is old and backport to anything prior to 737f2e93b972 ("ext2: convert to use the new truncate convention") will need these checks lifted into ext2_setattr().
