Josef Bacik 28546ac036 btrfs: reset RO counter on block group if we fail to relocate 
commit 74944c8736 upstream.

With the automatic block group reclaim code we will preemptively try to
mark the block group RO before we start the relocation.  We do this to
make sure we should actually try to relocate the block group.

However if we hit an error during the actual relocation we won't clean
up our RO counter and the block group will remain RO.  This was observed
internally with file systems reporting less space available from df when
we had failed background relocations.

Fix this by doing the dec_ro in the error case.

Fixes: 18bb8bbf13 ("btrfs: zoned: automatically reclaim zones")

README 

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.
