Subject: [PATCH 3/12] get_unmapped_area handles MAP_FIXED on arm
Date: Tue, 24 Apr 2007 15:33:35 +1000 [thread overview]
Message-ID: <20070424053337.C5FEBDDF09@ozlabs.org> (raw)
In-Reply-To: <1177392813.924664.32930750763.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.
