Hi, This series fixes a bug (see [1] for liburing patch) where the used buffer size is clamped to the minimum of all the previous buffers selected. It also as part of this forces the multishot read API to set addr & len to 0. len should probably have some accounting post-processing if it has meaning to set it to non-zero, but I think for a new API it is simpler to overly-constrain it upfront? addr is useful to force to zero as it will allow some more bits to be used in `struct io_rw`, which is otherwise full. v2: - apply comments - add a patch for io_kbuf_recycle to show if it did anything [1]: https://github.com/axboe/liburing/pull/981 Dylan Yudaken (3): io_uring: indicate if io_kbuf_recycle did recycle anything io_uring: do not allow multishot read to set addr or len io_uring: do not clamp read length for multishot read io_uring/kbuf.c | 6 +++--- io_uring/kbuf.h | 13 ++++++++----- io_uring/rw.c | 13 ++++++++++++- 3 files changed, 23 insertions(+), 9 deletions(-) base-commit: f688944cfb810986c626cb13d95bc666e5c8a36c -- 2.41.0
