We have btrfs_wait_ordered_roots() which takes a u64 for nr, but btrfs_start_delalloc_roots() that takes an int for nr, which makes using them in conjunction, especially for something like (u64)-1, annoying and inconsistent. Fix btrfs_start_delalloc_roots() to take a u64 for nr and adjust start_delalloc_inodes() and it's callers appropriately. This means we've adjusted start_delalloc_inodes() to take a pointer of nr since we want to preserve the ability for start-delalloc_inodes() to return an error, so simply make it do the nr adjusting as necessary. Part of adjusting the callers to this means changing btrfs_writeback_inodes_sb_nr() to take a u64 for items. This may be confusing because it seems unrelated, but the caller of btrfs_writeback_inodes_sb_nr() already passes in a u64, it's just the function variable that needs to be changed.

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.
