Since we have moved all other profiles handling into their own functions, now the main body of scrub_stripe() is just handling RAID56 profiles. There is no need to address other profiles in the main loop of scrub_stripe(), so we can remove those dead branches. Since we're here, also slightly change the timing of initialization of variables like @offset, @increment and @logical. Especially for @logical, we don't really need to initialize it for btrfs_extent_root()/btrfs_csum_root(), we can use bg->start for that purpose. Now those variables are only initialize for RAID56 branches. 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.
