There will be a followup one that adds discard support, but since that depends on both this branch and the block branch, it'll be sent post both of those. This pull request contains: - NAPI fixes and cleanups (Pavel, Olivier) - Add support for absolute timeouts (Pavel) - Fixes for io-wq/sqpoll affinities (Felix) - Efficiency improvements for dealing with huge pages (Chenliang) - Support for a minwait mode, where the application essentially has two timouts - one smaller one that defines the batch timeout, and the overall large one similar to what we had before. This enables efficient use of batching based on count + timeout, while still working well with periods of less intensive workloads. - Use ITER_UBUF for single segment sends - Add support for incremental buffer consumption. Right now each operation will always consume a full buffer. With incremental consumption, a recv/read operation only consumes the part of the buffer that it needs to satisfy the operation. - Add support for GCOV for io_uring, to help retain a high coverage of test to code ratio. - Fix regression with ocfs2, where an odd -EOPNOTSUPP wasn't correctly converted to a blocking retry. - Add support for cloning registered buffers from one ring to another. - Misc cleanups (Anuj, me) Please pull!
