Subject: [PATCH] cleanup root inode handling in xfs_fs_fill_super
Date: Wed, 19 Mar 2008 21:47:24 +0100 [thread overview]
Message-ID: <20080319204724.GA24271@lst.de> (raw)
- rename rootvp to root for clarify
- remove useless vn_to_inode call
- check is_bad_inode before calling d_alloc_root
- use iput instead of VN_RELE in the error case
