Naohiro Aota f4951c56d5 btrfs: zoned: fixup last alloc pointer after extent removal for DUP 
[ Upstream commit e2d848649e ]

When a block group is composed of a sequential write zone and a
conventional zone, we recover the (pseudo) write pointer of the
conventional zone using the end of the last allocated position.

However, if the last extent in a block group is removed, the last extent
position will be smaller than the other real write pointer position.
Then, that will cause an error due to mismatch of the write pointers.

We can fixup this case by moving the alloc_offset to the corresponding
write pointer position.

Fixes: c0d90a79e8 ("btrfs: zoned: fix alloc_offset calculation for partly conventional block groups")

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 reStructuredText 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.
