This is a note to let you know that I have just added a patch titled rbd: use GFP_NOIO in rbd_obj_request_create() to the linux-3.16.y-queue branch of the 3.16.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-3.16.y-queue This patch is scheduled to be released in version 3.16.7-ckt15. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.16.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From 257e02991d937936554e33b3cbab872fb836aed9 Mon Sep 17 00:00:00 2001 From: Ilya Dryomov <idryomov@gmail.com> Date: Wed, 24 Jun 2015 17:24:33 +0300 Subject: rbd: use GFP_NOIO in rbd_obj_request_create() commit 5a60e87603c4c533492c515b7f62578189b03c9c upstream. rbd_obj_request_create() is called on the main I/O path, so we need to use GFP_NOIO to make sure allocation doesn't blow back on us. Not all callers need this, but I'm still hardcoding the flag inside rather than making it a parameter because a) this is going to stable, and b) those callers shouldn't really use rbd_obj_request_create() and will be fixed in the future. More memory allocation fixes will follow.
