The new helper, submit_compressed_bio(), will aggregate the following work: - Increase compressed_bio::pending_bios - Remap the endio function - Map and submit the bio This slightly reorders calls to btrfs_csum_one_bio or btrfs_lookup_bio_sums but but none of them does anything regarding IO submission so this is effectively no change. We mainly care about order of - atomic_inc - btrfs_bio_wq_end_io - btrfs_map_bio Signed-off-by: Qu Wenruo <wqu@suse.com> Signed-off-by: David Sterba <dsterba@suse.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.
