This pull request contains: - io_uring: - The timeout command assumes sequence == 0 means that we want one completion, but this kind of overloading is unfortunate as it prevents users from doing a pure time based wait. Since this operation was introduced in this cycle, let's correct it now, while we can. (me) - One-liner to fix an issue with dependent links and fixed buffer reads. The actual IO completed fine, but the link got severed since we stored the wrong expected value. (me) - Add TIMEOUT to list of opcodes that don't need a file. (Pavel) - rsxx missing workqueue destry calls. Old bug. (Chuhong) - Fix blk-iocost active list check (Jiufei) - Fix impossible-to-hit overflow merge condition, that still hit some folks very rarely (Junichi) - Fix bfq hang issue from 5.3. This didn't get marked for stable, but will go into stable post this merge (Paolo) Please pull! git://git.kernel.dk/linux-block.git tags/for-linus-20191115 ---------------------------------------------------------------- Chuhong Yuan (1): rsxx: add missed destroy_workqueue calls in remove Jens Axboe (2): io_uring: make timeout sequence == 0 mean no sequence io_uring: ensure registered buffer import returns the IO length Jiufei Xue (1): iocost: check active_list of all the ancestors in iocg_activate() Junichi Nomura (1): block: check bi_size overflow before merge Paolo Valente (1): block, bfq: deschedule empty bfq_queues not referred by any process Pavel Begunkov (1): io_uring: Fix getting file for timeout block/bfq-iosched.c | 32 ++++++++++++++++++++++++++------ block/bio.c | 2 +- block/blk-iocost.c | 8 ++++++-- drivers/block/rsxx/core.c | 2 ++ fs/io_uring.c | 32 ++++++++++++++++++++++++-------- 5 files changed, 59 insertions(+), 17 deletions(-) -- Jens Axboe
