Subject: [PATCH 1/6] nilfs2: remove meaningless EBUSY case from nilfs_get_sb function
Date: Mon,  8 Jun 2009 01:39:28 +0900	[thread overview]
Message-ID: <1244392773-14230-2-git-send-email-konishi.ryusuke@lab.ntt.co.jp> (raw)
In-Reply-To: <1244392773-14230-1-git-send-email-konishi.ryusuke@lab.ntt.co.jp>

The following EBUSY case in nilfs_get_sb() is meaningless.  Indeed,
this error code is never returned to the caller.

    if (!s->s_root) {
          ...
    } else if (!(s->s_flags & MS_RDONLY)) {
        err = -EBUSY;
    }

This simply removes the else case.
