The reason why end_bbio_compressed_write() queues a work into compressed_write_workers wq is for end_compressed_writeback() call, as it will grab all the involved folios and clear the writeback flags, which may sleep. However now we always run btrfs_bio::end_io() in task context, there is no need to queue the work anymore. Just remove btrfs_fs_info::compressed_write_workers and compressed_bio::write_end_work. There is a comment about the works queued into compressed_write_workers, now change to flush endio wq instead, which is responsible to handle all data endio functions.

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.
