This pull request contains: - Remove a leftover struct from when the cqwait registered waiting was transitioned to regions. - Fix for an issue introduced in this merge window, where nop->fd might be used uninitialized. Ensure it's always set. - Add capping of the task_work run in local task_work mode, to prevent bursty and long chains from adding too much latency. - Work around xa_store() leaving ->head non-NULL if it encounters an allocation error during storing. Just a debug trigger, and can go away once xa_store() behaves in a more expected way for this condition. Not a major thing as it basically requires fault injection to trigger it. - Fix a few mapping corner cases - Fix KCSAN complaint on reading the table size post unlock. Again not a "real" issue, but it's easy to silence by just keeping the reading inside the lock that protects it. Please pull!

This pull request contains: - Fix for a file ref leak for registered ring fds - Turn the ->timeout_lock into a raw spinlock, as it nests under the io-wq lock which is a raw spinlock as it's called from the scheduler side - Limit ring resizing to DEFER_TASKRUN for now. We will broaden this in the future, but for now, ensure that it's only feasible on rings with a single user - Add sanity check for io-wq enqueuing Please pull!

Subject: [GIT PULL] io_uring fixes for 6.13-rc6 From: Jens Axboe To: Linus Torvalds Cc: io-uring Date: Fri, 3 Jan 2025 13:03:32 -0700 Hi Linus, A few fixes that should go into the 6.13-rc6 release, either fixing regressions in this cycle, or headed to stable. This pull request contains: - Fix an issue with the read multishot support and posting of CQEs from io-wq context. - Fix a regression introduced in this cycle, where making the timeout lock a raw one uncovered another locking dependency. As a result, move the timeout flushing outside of the timeout lock, punting them to a local list first. - Fix use of an uninitialized variable in io_async_msghdr. Doesn't really matter functionally, but silences a valid KMSAN complaint that it's not always initialized. - Fix use of incrementally provided buffers for read on non-pollable files, where the buffer always gets committed upfront. Unfortunately the buffer address isn't resolved first, so the read ends up using the updated rather than the current value. Please pull!

This pull request contains: - Fix for multishot timeout updates only using the updated value for the first invocation, not subsequent ones. - Silence a false positive lockdep warning - Fix the eventfd signaling and putting RCU logic - Fix fault injected SQPOLL setup not clearing the task pointer in the error path - Fix local task_work looking at the SQPOLL thread rather than just signaling the safe variant. Again one of those theoretical issues, which should be closed up none the less. Please pull!
