Subject: [PATCH 18/20] BKL: Remove BKL from do_new_mount()
Date: Wed, 18 Nov 2009 10:24:51 +0100 [thread overview]
Message-ID: <1258536293-7762-19-git-send-email-jblunck@suse.de> (raw)
In-Reply-To: <1258536293-7762-1-git-send-email-jblunck@suse.de>
After pushing down the BKL to the get_sb/fill_super operations of the
filesystems that still make usage of the BKL it is safe to remove it from
do_new_mount().
I've read through all the code formerly covered by the BKL inside
do_kern_mount() and have satisfied myself that it doesn't need the BKL
any more.
