Merge tag 'for-6.13/io_uring-20241118' of git://git.kernel.dk/linux
Pull io_uring updates from Jens Axboe: - Cleanups of the eventfd handling code, making it fully private. - Support for sending a sync message to another ring, without having a ring available to send a normal async message. - Get rid of the separate unlocked hash table, unify everything around the single locked one. - Add support for ring resizing. It can be hard to appropriately size the CQ ring upfront, if the application doesn't know how busy it will be. This results in applications sizing rings for the most busy case, which can be wasteful. With ring resizing, they can start small and grow the ring, if needed. - Add support for fixed wait regions, rather than needing to copy the same wait data tons of times for each wait operation. - Rewrite the resource node handling, which before was serialized per ring. This caused issues with particularly fixed files, where one file waiting on IO could hold up putting and freeing of other unrelated files. Now each node is handled separately. New code is much simpler too, and was a net 250 line reduction in code. - Add support for just doing partial buffer clones, rather than always cloning the entire buffer table. - Series adding static NAPI support, where a specific NAPI instance is used rather than having a list of them available that need lookup. - Add support for mapped regions, and also convert the fixed wait support mentioned above to that concept. This avoids doing special mappings for various planned features, and folds the existing registered wait into that too. - Add support for hybrid IO polling, which is a variant of strict IOPOLL but with an initial sleep delay to avoid spinning too early and wasting resources on devices that aren't necessarily in the < 5 usec category wrt latencies. - Various cleanups and little fixes. * tag 'for-6.13/io_uring-20241118' of git://git.kernel.dk/linux: (79 commits) io_uring/region: fix error codes after failed vmap io_uring: restore back registered wait arguments io_uring: add memory region registration io_uring: introduce concept of memory regions io_uring: temporarily disable registered waits io_uring: disable ENTER_EXT_ARG_REG for IOPOLL io_uring: fortify io_pin_pages with a warning switch io_msg_ring() to CLASS(fd) io_uring: fix invalid hybrid polling ctx leaks io_uring/uring_cmd: fix buffer index retrieval io_uring/rsrc: add & apply io_req_assign_buf_node() io_uring/rsrc: remove '->ctx_ptr' of 'struct io_rsrc_node' io_uring/rsrc: pass 'struct io_ring_ctx' reference to rsrc helpers io_uring: avoid normal tw intermediate fallback io_uring/napi: add static napi tracking strategy io_uring/napi: clean up __io_napi_do_busy_loop io_uring/napi: Use lock guards io_uring/napi: improve __io_napi_add io_uring/napi: fix io_napi_entry RCU accesses io_uring/napi: protect concurrent io_napi_entry timeout accesses ...
