Pull close_range() cleanup from Christian Brauner: "This is a cleanup for close_range() which was sent as part of a bugfix we did some time ago in commit9b5b872215("file: fix close_range() for unshare+cloexec"). We used to share more code between some helpers for close_range() which made retrieving the maximum number of open fds before calling into the helpers sensible. But with the introduction of CLOSE_RANGE_CLOEXEC and the need to retrieve the number of maximum fds once more for CLOSE_RANGE_CLOEXEC that stopped making sense. So the code was in a dumb in-limbo state. Fix this by simplifying the code a bit. The original idea was to only fix the bug itself and make backporting easy. And since the cleanup wasn't very pressing I left it in linux-next for a very long time. I didn't pull the patches from the list again back then which is why they don't have lore-links. So I'm listing them below explicitly" Commit03ba0fe4d0("file: simplify logic in __close_range()") Link: https://lore.kernel.org/linux-fsdevel/20210402123548.108372-3-brauner@kernel.org Commitf49fd6d3c0("file: let pick_file() tell caller it's done") Link: https://lore.kernel.org/linux-fsdevel/20210402123548.108372-4-brauner@kernel.org * tag 'fs.close_range.v5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: file: simplify logic in __close_range() file: let pick_file() tell caller it's done
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.
