Linux kernel source tree

We are passing a block reserve argument to btrfs_reserve_metadata_bytes() which is not really used, all we need is to pass the space_info associated to the block reserve, we don't change the block reserve at all. Not only it's pointless to pass the block reserve, it's also confusing as one might think that the reserved bytes will end up being added to the passed block reserve, when that's not the case. The pattern for reserving space and adding it to a block reserve is to first reserve space with btrfs_reserve_metadata_bytes() and if that succeeds, then add the space to a block reserve by calling btrfs_block_rsv_add_bytes(). Also the reverse of btrfs_reserve_metadata_bytes(), which is btrfs_space_info_free_bytes_may_use(), takes a space_info argument and not a block reserve, so one more reason to pass a space_info and not a block reserve to btrfs_reserve_metadata_bytes(). So change btrfs_reserve_metadata_bytes() and its callers to pass a space_info argument instead of a block reserve argument.

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.
