Currently btrfs_run_qgroups is doing a bit too much. Not only is it responsible for synchronizing in-memory state of qgroups to disk but it also contains code to trigger the initial qgroup rescan when quota is enabled initially. This condition is detected by checking that BTRFS_FS_QUOTA_ENABLED is not set and BTRFS_FS_QUOTA_ENABLING is set. Nothing really requires from the code to be structured (and scattered) the way it is so let's streamline things. First move the quota rescan code into btrfs_quota_enable, where its invocation is closer to the use. This also makes the FS_QUOTA_ENABLING flag redundant so let's remove it as well. This has been tested with a full xfstest run with qgroups enabled on the scratch device of every xfstest and no regressions were observed.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
