Pull io_uring fixes from Jens Axboe: - Fix an issue with discontig page checking for IORING_SETUP_NO_MMAP - Fix an issue with not allowing IORING_SETUP_NO_MMAP also disallowing mmap'ed buffer rings - Fix an issue with deferred release of memory mapped pages - Fix a lockdep issue with IORING_SETUP_NO_MMAP - Use fget/fput consistently, even from our sync system calls. No real issue here, but if we were ever to allow closing io_uring descriptors it would be required. Let's play it safe and just use the full ref counted versions upfront. Most uses of io_uring are threaded anyway, and hence already doing the full version underneath. * tag 'io_uring-6.7-2023-11-30' of git://git.kernel.dk/linux: io_uring: use fget/fput consistently io_uring: free io_buffer_list entries via RCU io_uring/kbuf: prune deferred locked cache when tearing down io_uring/kbuf: recycle freed mapped buffer ring entries io_uring/kbuf: defer release of mapped buffer rings io_uring: enable io_mem_alloc/free to be used in other parts io_uring: don't guard IORING_OFF_PBUF_RING with SETUP_NO_MMAP io_uring: don't allow discontig pages for IORING_SETUP_NO_MMAP
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 Restructured Text 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.
