From b42d9165e1e3d92e4e3318642463dbe592a12568 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Tue, 1 Jun 2010 00:26:06 -0700 Subject: drivers/isdn/hardware/mISDN: Use GFP_ATOMIC when a lock is held The function inittiger is only called from nj_init_card, where a lock is held. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // @gfp exists@ identifier fn; position p; @@ fn(...) { ... when != spin_unlock_irqrestore when any GFP_KERNEL@p ... when any } @locked@ identifier gfp.fn; @@ spin_lock_irqsave(...) ... when != spin_unlock_irqrestore fn(...) @depends on locked@ position gfp.p; @@ - GFP_KERNEL@p + GFP_ATOMIC // Signed-off-by: Julia Lawall Signed-off-by: David S.
