Subject: [PATCH 3/12] get_unmapped_area handles MAP_FIXED on arm
Date: Thu, 12 Apr 2007 12:20:28 +1000 [thread overview]
Message-ID: <20070412022030.976C9DDF27@ozlabs.org> (raw)
In-Reply-To: <1176344427.242579.337989891532.qpush@grosgo>
ARM already had a case for MAP_FIXED in arch_get_unmapped_area() though
it was not called before. Fix the comment to reflect that it will now
be called.
