btree updates before going RW are expensive if they're in random order, since they use the list of keys for journal replay to insert, which is just a gap buffer. This patch improves the bucket invalidate path so that if bch2_check_lrus() hasn't finished it only prints warnings instead of doing an emergency shutdown, which means we can now set BCH_FS_MAY_GO_RW before bch2_check_lrus(). Also, the filesystem state bits are reorganized a bit. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
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.
