This includes the following changes: - Implement new raid_unplug() functions Now we don't need a workqueue to run the plug, as all our work is just queue rmw_rbio_work() call, which can be executed without sleep. - Implement a rmw_rbio_work_locked() helper This is for unlock_stripe(), which is already holding the full stripe lock. - Remove all the old functions This should already shows how complex the old functions are, as we ended up removing the following functions: * rmw_work() * validate_rbio_for_rmw() * raid56_rmw_end_io_work() * raid56_rmw_stripe() * full_stripe_write() * partial_stripe_write() * __raid56_parity_write() * run_plug() * unplug_work() * btrfs_raid_unplug() * rmw_work() * __raid56_parity_recover() * raid_recover_end_io_work() - Unexport rmw_rbio() 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.
