Subject: [PATCH 10/10] btrfs: Remove redundant argument of __link_block_group
Date: Mon, 21 Aug 2017 12:43:50 +0300	[thread overview]
Message-ID: <1503308630-6652-11-git-send-email-nborisov@suse.com> (raw)
In-Reply-To: <1503308630-6652-1-git-send-email-nborisov@suse.com>

__link_block_group is called from only 2 places and at each call site the
space_info being passed is the same as the space info assigned to the passed
cache struct. Let's remove the redundant argument and make the function
reference the space_info from the passed block_group_cache. No functional
changes
