parentio_uring: fix io_sq_thread_stop running in front of io_sq_thread (diff)
Merge tag 'for-5.3/io_uring-20190711' of git://git.kernel.dk/linux-block
Pull io_uring updates from Jens Axboe: "This contains: - Support for recvmsg/sendmsg as first class opcodes. I don't envision going much further down this path, as there are plans in progress to support potentially any system call in an async fashion through io_uring. But I think it does make sense to have certain core ops available directly, especially those that can support a "try this non-blocking" flag/mode. (me) - Handle generic short reads automatically. This can happen fairly easily if parts of the buffered read is cached. Since the application needs to issue another request for the remainder, just do this internally and save kernel/user roundtrip while providing a nicer more robust API. (me) - Support for linked SQEs. This allows SQEs to depend on each other, enabling an application to eg queue a read-from-this-file,write-to-that-file pair. (me) - Fix race in stopping SQ thread (Jackie)" * tag 'for-5.3/io_uring-20190711' of git://git.kernel.dk/linux-block: io_uring: fix io_sq_thread_stop running in front of io_sq_thread io_uring: add support for recvmsg() io_uring: add support for sendmsg() io_uring: add support for sqe links io_uring: punt short reads to async context uio: make import_iovec()/compat_import_iovec() return bytes on success
