The function rbio_bio_add_io_paddr() assume each fs block can be mapped by one page, blocking bs > ps support for raid56. Prepare it for bs > ps cases by: - Introduce a helper bio_add_paddrs() Previously we only need to add a single page to a bio for a fs block, but now we need to add multiple pages, this means we can fail halfway. In that case we need to properly revert the bio (only for its size though) for halfway failed cases. - Rename rbio_add_io_paddr() to rbio_add_io_paddrs() And change the @paddr parameter to @paddrs[]. - Change all callers to use the updated rbio_add_io_paddrs() For the @paddrs pointer used for the new function, it can be grabbed using sector_paddrs_in_rbio() and rbio_stripe_paddrs() helpers.

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 reStructuredText 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.
