Date: Thu, 21 Feb 2013 15:57:21 +0400 From: Denis Efremov <yefremov.denis@...il.com> To: Neela Syam Kolli <megaraidlinux@....com> Cc: Denis Efremov <yefremov.denis@...il.com>, linux-scsi@...r.kernel.org, linux-kernel@...r.kernel.org, ldv-project@...uxtesting.org Subject: [PATCH] [SCSI]: megaraid: avoid sleeping on spinlock GFP_KERNEL may cause pci_pool_alloc() sleep, so we need use GFP_ATOMIC instead of GFP_KERNEL.
