staging: Use GFP_ATOMIC when a lock is held
In each case, the containing function is only called from one place, where a spin lock is held. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @gfp exists@ identifier fn; position p; @@ fn(...) { ... when != spin_unlock when any GFP_KERNEL@p ... when any } @locked@ identifier gfp.fn; @@ spin_lock(...) ... when != spin_unlock fn(...) @depends on locked@ position gfp.p; @@ - GFP_KERNEL@p + GFP_ATOMIC // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Cc: Jonathan Cameron <jic23@cam.ac.uk> Cc: Marek Lindner <lindner_marek@yahoo.de> Cc: Martyn Welch <martyn.welch@ge.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
