When we're (re)mounting a btrfs filesystem we set the BTRFS_FS_STATE_REMOUNTING state in fs_info to serialize against async reclaim or defrags. This flag is set in btrfs_remount_prepare() called by btrfs_remount(). As btrfs_remount_prepare() does nothing but setting this flag and doesn't have a second caller, we can just open-code the flag setting in btrfs_remount(). Similarly do for so clearing of the flag by moving it out of btrfs_remount_cleanup() into btrfs_remount() to be symmetrical.

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.
