Date: Sun, 4 Mar 2012 14:23:00 +0100 From: Stefan Richter <stefanr@...6.in-berlin.de> To: linux1394-devel@...ts.sourceforge.net Cc: linux-kernel@...r.kernel.org Subject: [PATCH] firewire: sbp2: replace a GFP_ATOMIC allocation sbp2_send_management_orb() is called by sbp2_login, sbp2_reconnect, and sbp2_remove, all which are able to sleep during memory allocations. Actually, sbp2_send_management_orb() itself is a sleeping function. Login and remove could allocate with GFP_KERNEL but reconnect needs GFP_NOIO to ensure progress in low memory situations.
