It is very normal to see allocation failure, especially with blk-mq request_queues, so it's unnecessary to report this error and annoy people. In practice this 'blk_get_request() returned -11' error gets logged quite frequently when a blk-mq DM multipath device sees heavy IO. This change is marked for stable@ because the annoying message in question was included in stable@ commit7083abbbf. Fixes:7083abbbf("dm mpath: avoid that path removal can trigger an infinite loop") Cc: stable@vger.kernel.org Signed-off-by: Ming Lei <ming.lei@redhat.com> Signed-off-by: Mike Snitzer <snitzer@redhat.com>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
