This is the fs/ part of the big kfree cleanup patch.
Remove pointless checks for NULL prior to calling kfree() in fs/.
Sorry about the long Cc: list, but I wanted to make sure I included everyone
who's code I've changed with this patch.
Signed-off-by: Jesper Juhl <[EMAIL PROTECTED]>

"[PATCH 00/14] Big kfree NULL check cleanup"
