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.

commit 50ff5788 upstream. On a zoned filesystem, if we fail to allocate the root node for the log root tree while syncing the log, we end up returning without finishing the IO plug we started before, resulting in leaking resources as we have started writeback for extent buffers of a log tree before. That allocation failure, which typically is either -ENOMEM or -ENOSPC, is not fatal and the fsync can safely fallback to a full transaction commit. So release the IO plug if we fail to allocate the extent buffer for the root of the log root tree when syncing the log on a zoned filesystem. Fixes: 3ddebf27 ("btrfs: zoned: reorder log node allocation on zoned filesystem") CC: stable@vger.kernel.org # 5.15+ Reviewed-by:Johannes Thumshirn <johannes.thumshirn@wdc.com> Signed-off-by:
