In open_ctree, we set BTRFS_FS_QUOTA_ENABLED as soon as we see a quota_root, as opposed to after we are done setting up the qgroup structures. In the quota_enable path, we wait until after the structures are set up. Likewise, in disable, we clear the bit before tearing down the structures. I feel that this organization is less surprising for the open_ctree path. I don't believe this fixes any actual bug, but avoids potential confusion when using btrfs_qgroup_mode in an intermediate state where we are enabled but haven't yet setup the qgroup status flags. It also avoids any risk of calling a qgroup function and attempting to use the qgroup rbtrees before they exist/are setup. This all occurs before we do rw setup, so I believe it should be mostly a no-op. Signed-off-by: Boris Burkov <boris@bur.io> Signed-off-by: David Sterba <dsterba@suse.com> |

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.
