Subject: [PATCH 3/4] exit: Rename assign_new_owner label in mm_update_next_owner()
Date: Thu, 26 Apr 2018 14:00:59 +0300	[thread overview]
Message-ID: <152474045969.29458.5499629495380211357.stgit@localhost.localdomain> (raw)
In-Reply-To: <152473763015.29458.1131542311542381803.stgit@localhost.localdomain>

Next patch introduces nolock variant of this label,
so we will have new_owner and new_owner_nolock.
assign_new_owner_nolock would be too long there.
