When the number the bands of sch_prio is decreased, child qdiscs on the deleted bands would get deleted as well. This change and deletions are being done under sch_tree_lock of the sch_prio qdisc. Part of the destruction of qdisc is unoffloading it, if it is offloaded. Un-offloading can't be done inside this lock. Move the offload command to be done before reducing the number of bands, so unoffloading of the qdiscs that are about to be deleted could be done outside of the lock.

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.
