Although we have btrfs_requeue_inode_defrag(), for autodefrag we are still just exhausting all inode_defrag items in the tree. This means, it doesn't make much difference to requeue an inode_defrag, other than scan the inode from the beginning till its end. Change the behaviour to always scan from offset 0 of an inode, and till the end. By this we get the following benefit: - Straight-forward code - No more re-queue related check - Fewer members in inode_defrag We still keep the same btrfs_get_fs_root() and btrfs_iget() check for each loop, and added extra should_auto_defrag() check per-loop. Note: the patch needs to be backported and is intentionally written to minimize the diff size, code will be cleaned up later.

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.
