The allocation and initialization is shared by 3 call sites, and we're going to change the initialization of some members in the upcoming patches. So factor out the allocation and initialization of scrub_sector into a helper, alloc_scrub_sector(), which will do the following work: - Allocate the memory for scrub_sector - Allocate a page for scrub_sector::page - Initialize scrub_sector::refs to 1 - Attach the allocated scrub_sector to scrub_block The attachment is bidirectional, which means scrub_block::sectorv[] will be updated and scrub_sector::sblock will also be updated. - Update scrub_block::sector_count and do extra sanity check on it Signed-off-by: Qu Wenruo <wqu@suse.com> Reviewed-by: David Sterba <dsterba@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.
