The allocator thread invalidates buckets (increments their generation number) prior to discarding them and putting them on freelists. We've had a short circuit path for some time to only update the in-memory bucket mark when doing the invalidate if we're not invalidating cached data, but that short-circuit path hasn't really been needed for quite some time (likely since the btree key cache code was added). We're deleting it now as part of deleting/converting code that uses the in memory bucket array. 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.
