From: Julia Lawall Date: Mon, 9 Jan 2012 09:40:47 +0000 (+0100) Subject: IB/qib: Use GFP_ATOMIC when locks are held X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0f3696eb21ef39b7bb7ea7d0160e925904309281;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git IB/qib: Use GFP_ATOMIC when locks are held alloc_dummy_hdrq() is called with locks held and thus should not use GFP_KERNEL. The semantic patch that makes this report is available in scripts/coccinelle/locks/call_kern.cocci.
