Subject: [PATCH] btrfs: Use locked_end rather than open coding it
Date: Wed,  1 Nov 2017 11:36:05 +0200	[thread overview]
Message-ID: <1509528965-4818-1-git-send-email-nborisov@suse.com> (raw)

Right before we go into this loop locked_end is set to alloc_end - 1 and is
being used in nearby functions, no need to have exceptions. This just makes the
code consistent, no functional changes
