Pull btrfs fixes from David Sterba:
"Here are two fixes, one of them urgent fixing a bug introduced in 5.2
and reported by many users. It took time to identify the root cause,
catching the 5.3 release is higly desired also to push the fix to 5.2
stable tree.
The bug is a mess up of return values after adding proper error
handling and honestly the kind of bug that can cause sleeping
disorders until it's caught. My appologies to everybody who was
affected.
Summary of what could happen:
1) either a hang when committing a transaction, if this happens
there's no risk of corruption, still the hang is very inconvenient
and can't be resolved without a reboot
2) writeback for some btree nodes may never be started and we end up
committing a transaction without noticing that, this is really
serious and that will lead to the "parent transid verify failed"
messages"
* tag 'for-5.3-rc8-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux:
Btrfs: fix unwritten extent buffers and hangs on future writeback attempts
Btrfs: fix assertion failure during fsync and use of stale transaction
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.
