commit64ebe12494upstream. From kernel 4.9, my two nfsv4 servers sometimes suffer from "panic: unable to handle kernel page request" in posix_unblock_lock() called from nfs4_laundromat(). These panics diseappear if we revert the commit "nfsd: add a LRU list for blocked locks". The cause appears to be a typo in nfs4_laundromat(), which is also present in nfs4_state_shutdown_net().

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.
