[ Upstream commit 57d4f0b863272ba04ba85f86bfdc0f976f0af91c ] Currently, scrub_missing_raid56_worker() puts and potentially frees sblock (which embeds the work item) and then submits a bio through scrub_wr_submit(). This is another potential instance of the bug in "btrfs: don't prematurely free work in run_ordered_work()". Fix it by dropping the reference after we submit the bio.

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.
