| liburing-2.2 release |
| |
| - Support non-libc builds. |
| - Optimized syscall handling for x86-64/x86/aarch64. |
| - Enable non-lib function calls for fast path functions. |
| - Add support for multishot accept. |
| - io_uring_register_files() will set RLIMIT_NOFILE if necessary. |
| - Add support for registered ring fds, io_uring_register_ring_fd(), |
| reducingthe overhead of an io_uring_enter() system call. |
| - Add support for the message ring opcode. |
| - Add support for newer request cancelation features. |
| - Add support for IORING_SETUP_COOP_TASKRUN, which can help reduce the |
| overhead of io_uring in general. Most applications should set this flag, |
| see the io_uring_setup.2 man page for details. |
| - Add support for registering a sparse buffer and file set. |
| - Add support for a new buffer provide scheme, see |
| io_uring_register_buf_ring.3 for details. |

| for completions with a timeout. |
| - Add io_uring_prep_{read,write}v2 prep helpers. |
| - Add io_uring_prep_close_direct() helper. |
| - Add support for SQE128 and CQE32, which are doubly sized SQE and CQE |
| rings. This is needed for some cases of the new IORING_OP_URING_CMD, |
| notably for NVMe passthrough. |
| - ~5500 lines of man page additions, including adding ~90 new man pages. |
| - Synced with the 5.19 kernel release, supporting all the features of |
