2023-01-30io_uring: Rename struct io_op_defBreno Leitao5-25/+25
The current io_op_def struct is becoming huge and the name is a bit generic. The goal of this patch is to rename this struct to `io_issue_def`. This struct will contain the hot functions associated with the issue code path. For now, this patch only renames the structure, and an upcoming patch will break up the structure in two, moving the non-issue fields to a secondary struct.

2023-01-30io_uring: optimise ctx flags layoutPavel Begunkov1-3/+3
There may be different cost for reeading just one byte or more, so it's benificial to keep ctx flag bits that we access together in a single byte. That affected code generation of __io_cq_unlock_post_flush() and removed one memory load.

Lock the ring with uring_lock in io_fallback_req_func(), which should make it a bit safer and easier.

io_submit_flush_completions() may queue new requests for tw execution, especially true for linked requests. Recheck the tw list for emptiness after flushing completions.

2023-01-30io_uring: optimise deferred tw executionPavel Begunkov1-17/+7
We needed fake nodes in __io_run_local_work() and to avoid unecessary wake ups while the task already running task_works, but we don't need them anymore since wake ups are protected by cq_waiting, which is always cleared by the time we're executing deferred task_work items. Note that because of loose sync around cq_waiting clearing io_req_local_work_add() may wake the task more than once, but that's fine and should be rare to not hurt perf.

2023-01-30io_uring: waitqueue-less cq waitingPavel Begunkov1-7/+12
With DEFER_TASKRUN only ctx->submitter_task might be waiting for CQEs, we can use this to optimise io_cqring_wait(). Replace ->cq_wait waitqueue with waking the task directly. It works but misses an important optimisation covered by the following patch, so this patch without follow ups might hurt performance.

2023-01-30io_uring: wake up optimisationsPavel Begunkov1-1/+20
Flush completions is done either from the submit syscall or by the task_work, both are in the context of the submitter task, and when it goes for a single threaded rings like implied by ->task_complete, there won't be any waiters on ->cq_wait but the master task. That means that there can be no tasks sleeping on cq_wait while we run __io_submit_flush_completions() and so waking up can be skipped.

2023-01-30io_uring: add lazy poll_wq activationPavel Begunkov3-5/+64
Even though io_poll_wq_wake()'s waitqueue_active reuses a barrier we do for another waitqueue, it's not going to be the case in the future and so we want to have a fast path for it when the ring has never been polled. Move poll_wq wake ups into __io_commit_cqring_flush() using a new flag called ->poll_activated. The idea behind the flag is to set it when the ring was polled for the first time. This requires additional sync to not miss events, which is done here by using task_work for ->task_complete rings, and by default enabling the flag for all other types of rings.

2023-01-30io_uring/msg_ring: Pass custom flags to the cqeBreno Leitao2-5/+21
This patch adds a new flag (IORING_MSG_RING_FLAGS_PASS) in the message ring operations (IORING_OP_MSG_RING). This new flag enables the sender to specify custom flags, which will be copied over to cqe->flags in the receiving ring. These custom flags should be specified using the sqe->file_index field.

2023-01-29Revert "mm/compaction: fix set skip in fast_find_migrateblock"Vlastimil Babka1-0/+1
This reverts commit 7efc3b7261030da79001c00d92bc3392fd6c664c. We have got openSUSE reports (Link 1) for 6.1 kernel with khugepaged stalling CPU for long periods of time. Investigation of tracepoint data shows that compaction is stuck in repeating fast_find_migrateblock() based migrate page isolation, and then fails to migrate all isolated pages. Commit 7efc3b726103 ("mm/compaction: fix set skip in fast_find_migrateblock") was suspected as it was merged in 6.1 and in theory can indeed remove a termination condition for fast_find_migrateblock() under certain conditions, as it removes a place that always marks a scanned pageblock from being re-scanned. There are other such places, but those can be skipped under certain conditions, which seems to match the tracepoint data. Testing of revert also appears to have resolved the issue, thus revert the commit until a more robust solution for the original problem is developed. It's also likely this will fix qemu stalls with 6.1 kernel reported in Link 2, but that is not yet confirmed.
