- In check_alloc_key(), previously we were re-initializing iterators for the need_discard and freespace btrees for every alloc key we checked. But this was causing us to redo lookups into the journal keys every time, since those lookups are cached in struct btree_iter. This initializes the iterators in bch2_check_alloc_info and passes them into check_alloc_key(). - Make the looping more consistent/efficient in bch2_check_alloc_info() 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.
