From 39f77adb32b2939a0c5ffd2cbbe0600a0a83e00b Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Thu, 26 Mar 2009 14:31:08 +0000 Subject: allow v4l2 drivers to provide a get_unmapped_area handler MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit From: Daniel Glöckner Shared memory mappings on nommu machines require a get_unmapped_area file operation that suggests an address for the mapping. This patch adds a way for v4l2 drivers to provide this callback.
