- Fix a rare emergency shutdown path bug: dropping journal pins after
the filesystem has mostly been torn down is not what we want.
- Fix some concurrency issues with the btree write buffer and journal
replay by not using the btree write buffer until journal replay is
finished
- A fixup from the prior patch to kill journal pre-reservations: at the
start of the btree update path, where previously we took a
pre-reservation, we do at least want to check the journal watermark.
- Fix a race between dropping device metadata and btree node writes,
which would re-add a pointer to a device that had just been dropped
- Fix one of the SCRU lock warnings, in
bch2_compression_stats_to_text().
- Partial fix for a rare transaction paths overflow, when indirect
extents had been split by background tasks, by not running certain
triggers when they're not needed.
- Fix for creating a snapshot with implicit source in a subdirectory of
the containing subvolume
- Don't unfreeze when we're emergency read-only
- Fix for rebalance spinning trying to compress unwritten extentns
- Another deleted_inodes fix, for directories
- Fix a rare deadlock (usually just an unecessary wait) when flushing
the journal with an open journal entry.

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.
