linux-toradex.git/block/blk-ioc.c, branch v2.6.25.18 Linux kernel for Apalis and Colibri modules cfq-iosched: add hlist for browsing parallel to the radix tree 2008-02-19T09:04:00+00:00 Jens Axboe jens.axboe@oracle.com 2008-02-19T09:02:29+00:00 ffc4e7595734cf768fa60cea8a4d545dfef8231a It's cumbersome to browse a radix tree from start to finish, especially since we modify keys when a process exits. So add a hlist for the single purpose of browsing over all known cfq_io_contexts, used for exit, io prio change, etc. This fixes http://bugzilla.kernel.org/show_bug.cgi?id=9948 Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

That doesn't work so well for either lock ordering or lockdep. There seems zero point in swapping io contexts on a request to request merge, so the best point of action is to just remove it.
