commit 37f96694cf73ba116993a9d2d99ad6a75fa7fdb0 upstream. As af_alg_release_parent may be called from BH context (most notably due to an async request that only completes after socket closure, or as reported here because of an RCU-delayed sk_destruct call), we must use bh_lock_sock instead of lock_sock.

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.
