Currently inside alloc_rbio(), we allocate a larger memory to contain the following members: - struct btrfs_raid_rbio itself - stripe_pages array - bio_sectors array - stripe_sectors array - finish_pointers array Then update rbio pointers to point the extra space after the rbio structure itself. Thus it introduced a complex CONSUME_ALLOC() macro to help the thing. This is too hacky, and is going to make later pointers expansion harder. This patch will change it to use regular kcalloc() for each pointer inside btrfs_raid_bio, making the later expansion much easier. And introduce a helper free_raid_bio_pointers() to free up all the pointer members in btrfs_raid_bio, which will be used in both free_raid_bio() and error path of alloc_rbio().

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.
