Implement a hash table, using cuckoo hashing, for empty buckets that are waiting on a journal commit before they can be reused. This replaces the journal_seq field of bucket_mark, and is part of eventually getting rid of the in memory bucket array. We may need to make bch2_bucket_needs_journal_commit() lockless, pending profiling and testing. 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.
