This is how these buffers were handled prior to having cloning support, and we can still use that approach as long as the buffers haven't been cloned to another ring. - Cleanup and improvement for uring_cmd, where btrfs was the only user of storing allocated data for the lifetime of the uring_cmd. Clean that up so we can get rid of the need to do that. - Avoid unnecessary memory copies in uring_cmd usage. This is particularly important as a lot of uring_cmd usage necessitates the use of 128b SQEs. - A few updates for recv multishot, where it's now possible to add fairness limits for limiting how much is transferred for each retry loop. Additionally, recv multishot now supports an overall cap as well, where once reached the multishot recv will terminate. The latter is useful for buffer management and juggling many recv streams at the same time. - Add support for returning the TX timestamps via a new socket command. This feature can work in either singleshot or multishot mode, where the latter triggers a completion whenever new timestamps are available. This is an alternative to using the existing error queue. - Add support for an io_uring "mock" file, which is the start of being able to do 100% targeted testing in terms of exercising io_uring request handling. The idea is to have a file type that can be anything the tester would like, and behave exactly how you want it to behave in terms of hitting the code paths you want. - Improve zcrx by using sgtables to de-duplicate and improve dma address handling. - Prep work for supporting larger pages for zcrx. - Various little improvements and fixes. * tag 'for-6.17/io_uring-20250728' of git://git.kernel.dk/linux: (42 commits) io_uring/zcrx: fix leaking pages on sg init fail io_uring/zcrx: don't leak pages on account failure io_uring/zcrx: fix null ifq on area destruction io_uring: fix breakage in EXPERT menu io_uring/cmd: remove struct io_uring_cmd_data btrfs/ioctl: store btrfs_uring_encoded_data in io_btrfs_cmd io_uring/cmd: introduce IORING_URING_CMD_REISSUE flag io_uring/zcrx: account area memory io_uring: export io_[un]account_mem io_uring/net: Support multishot receive len cap io_uring: deduplicate wakeup handling io_uring/net: cast min_not_zero() type io_uring/poll: cleanup apoll freeing io_uring/net: allow multishot receive per-invocation cap io_uring/net: move io_sr_msg->retry_flags to io_sr_msg->flags io_uring/net: use passed in 'len' in io_recv_buf_select() io_uring/zcrx: prepare fallback for larger pages io_uring/zcrx: assert area type in io_zcrx_iov_page io_uring/zcrx: allocate sgtable for umem areas io_uring/zcrx: introduce io_populate_area_dma ... |

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
