Subject: [PATCH 02/10] mm: remove __vfree
Date: Sat, 21 Jan 2023 08:10:43 +0100	[thread overview]
Message-ID: <20230121071051.1143058-3-hch@lst.de> (raw)
In-Reply-To: <20230121071051.1143058-1-hch@lst.de>

__vfree is a subset of vfree that just skips a few checks, and which is
only used by vfree and an error cleanup path.  Fold __vfree into vfree
and switch the only other caller to call vfree() instead.
