Assorted bugfixes. Most are fixes for simple assertion pops; the most significant fix is for a deadlock in recovery when we have to rewrite large numbers of btree nodes to fix errors. This was incorrectly running out of the same workqueue as the core interior btree update path - we now give it its own single threaded workqueue. This was visible to users as "bch2_btree_update_start(): error: BCH_ERR_journal_reclaim_would_deadlock" - and then recovery hanging. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEKnAFLkS8Qha+jvQrE6szbY3KbnYFAmX6CoYACgkQE6szbY3K bnZp2hAAwAw8haQKeR0+0aAaqTavvBcjcloeKlQhRl+OxV1rAgxcjKGai5txZ9rI d4FVOOo7MqHq1oN9Ydsy1+0R70eCFzhDxhT1Ph5MhIzc7nd8lC0GQjO0atx23cni 4UZgSxi6quEP401MTVhvVbCPLmvfPJLpIBzptJUDS/eysxSZpS4A10gEzipoNjPv DOdrsvoo8nQX53tERJ/IxtroFL44p4y8OyZK65NILFF9xZosKz1P9ktrWufmRVoY /Hl8SUfhSNJDFW5pIMPOmoG/+RG+hJK4BaiNWPXLaSvO+3PmQskJ2tvHQVNjHQYt dMYWcy4hN47XtYvrHG9xmaQP+lZCDijdBrhmik4brqfZbloH43MVdDFysjfIPhUm qk+zzb0uE0ZhwRvQOjnYEQpHjXmj7Bm80+dhfNuuiKlhz4bOeDz8UZykJOzgD0zH n4cd+nbCxuogkukzLLQMbFv1+MCsCZpStkXP3GQXCK0k+H2briPGALuA74sxfAhH ajHLNr6qMU+uB6Ce0oM7e+9dPLfV/NalEwWW7aR/4TamxPBt575Hpjp0BV//BRfD IxdEKrMNdbKBJDUj1s5aTwcSF6ae6zHtyQXuKr93mWQqNvVXvX5/FPQYr70uA1VP iieBkde7aSTGCbTdTEcY9NcXdT2X/91aobsPvwGeq1z5Y1JJ0nU= =J/hu -----END PGP SIGNATURE----- Merge tag 'bcachefs-2024-03-19' of https://evilpiepirate.org/git/bcachefs Pull bcachefs fixes from Kent Overstreet: "Assorted bugfixes.

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.
