From bc077320f8f6449197f4010d6774afab7bb998b2 Mon Sep 17 00:00:00 2001 From: Marco Stornelli Date: Sat, 20 Oct 2012 12:02:59 +0200 Subject: hostfs: fix a not needed double check With the commit 3be2be0a32c18b0fd6d623cda63174a332ca0de1 we removed vmtruncate, but actaully there is no need to call inode_newsize_ok() because the checks are already done in inode_change_ok() at the begin of the function.

(Part 3) Somehow I failed to add the MODULE_ALIAS_FS for cifs, hostfs, hpfs, squashfs, and udf despite what I thought were my careful checks :( Add them now. Signed-off-by: "Eric W.
