Theodore Ts'o b50282f324 ext4: check to make sure the rename(2)'s destination is not freed
If the destination of the rename(2) system call exists, the inode's
link count (i_nlinks) must be non-zero.  If it is, the inode can end
up on the orphan list prematurely, leading to all sorts of hilarity,
including a use-after-free.
