Boris Burkov bf1e8c21f2 btrfs: retry block group reclaim without infinite loop commit `4eb4e85c4f` upstream. If inc_block_group_ro systematically fails (e.g. due to ETXTBUSY from swap) or btrfs_relocate_chunk systematically fails (from lack of space), then this worker becomes an infinite loop. At the very least, this strands the cleaner thread, but can also result in hung tasks/RCU stalls on PREEMPT_NONE kernels and if the reclaim_bgs_lock mutex is not contended. I believe the best long term fix is to manage reclaim via work queue, where we queue up a relocation on the triggering condition and re-queue on failure. In the meantime, this is an easy fix to apply to avoid the immediate pain.

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.
