bytes_pinned is always accessed under space_info->lock, except in btrfs_preempt_reclaim_metadata_space, however the other members are accessed under that lock. The reserved member of the rsv's are also partially accessed under a lock and partially not. Move all these accesses into the same lock to ensure consistency. This could potentially race and lead to a flush instead of a commit but it's not a big problem as it's only for preemptive flush.

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.
