Commit5d23515be6("btrfs: Move qgroup rescan on quota enable to btrfs_quota_enable") not only resulted in an easier to follow code but it also introduced a subtle bug. It changed the timing when the initial transaction rescan was happening: - before the commit: it would happen after transaction commit had occured - after the commit: it might happen before the transaction was committed This results in failure to correctly rescan the quota since there could be data which is still not committed on disk. This patch aims to fix this by moving the transaction creation/commit inside btrfs_quota_enable, which allows to schedule the quota commit after the transaction has been committed.

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.
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.
