Subject: [PATCH V2] xfs: don't ASSERT on corrupt ftype
Date: Mon, 08 Sep 2014 17:18:07 -0500	[thread overview]
Message-ID: <540E2B1F.9070009@sandeen.net> (raw)
In-Reply-To: <540D011B.2000807@redhat.com>

xfs_dir3_data_get_ftype() gets the file type off
disk, but ASSERTs if it's invalid:

     ASSERT(type < XFS_DIR3_FT_MAX);

We shouldn't ASSERT on bad values read from disk.
V3 dirs are CRC-protected, but V2 dirs + ftype
are not.
