Subject: [RFC] gfp flags annotations - part 3 (simple parts of mm/*)
Date: Sun, 9 Oct 2005 06:35:16 +0100 [thread overview]
Message-ID: <20051009053516.GH7992@ftp.linux.org.uk> (raw)
In-Reply-To: <Pine.LNX.4.64.0510081630030.31407@g5.osdl.org>
A bunch of unsigned int -> gfp_t in mm/*. All tricky parts
(zone handling) are left as-is - we'll deal with them later. This
is just the missing annotations.
