In detail: - Followup fixes to patches from last week for io-wq, turns out they weren't complete (Hao) - Two lockdep reported fixes out of the RT camp (me) - Sync the io_uring-cp example with liburing, as a few bug fixes never made it to the kernel carried version (me) - SQPOLL related TIF_NOTIFY_SIGNAL fix (Nadav) - Use WRITE_ONCE() when writing sq flags (Nadav) - io_rsrc_put_work() deadlock fix (Pavel) Please pull! The following changes since commit 21698274da5b6fc724b005bc7ec3e6b9fbcfaa06: io-wq: fix lack of acct->nr_workers < acct->max_workers judgement (2021-08-06 08:28:18 -0600) are available in the Git repository at: git://git.kernel.dk/linux-block.git tags/io_uring-5.14-2021-08-13 for you to fetch changes up to 8f40d0370795313b6f1b1782035919cfc76b159f: tools/io_uring/io_uring-cp: sync with liburing example (2021-08-13 08:58:11 -0600) ---------------------------------------------------------------- io_uring-5.14-2021-08-13 ---------------------------------------------------------------- Hao Xu (2): io-wq: fix bug of creating io-wokers unconditionally io-wq: fix IO_WORKER_F_FIXED issue in create_io_worker() Jens Axboe (3): io_uring: rsrc ref lock needs to be IRQ safe io_uring: drop ctx->uring_lock before flushing work item tools/io_uring/io_uring-cp: sync with liburing example Nadav Amit (2): io_uring: clear TIF_NOTIFY_SIGNAL when running task work io_uring: Use WRITE_ONCE() when writing to sq_flags Pavel Begunkov (1): io_uring: fix ctx-exit io_rsrc_put_work() deadlock fs/io-wq.c | 26 ++++++++++++++------ fs/io_uring.c | 58 ++++++++++++++++++++++---------------------- tools/io_uring/io_uring-cp.c | 31 ++++++++++++++++++++--- 3 files changed, 75 insertions(+), 40 deletions(-) -- Jens Axboe
