lockd_inet[6]addr_event use nlmsvc_rqst without taken nlmsvc_mutex, nlmsvc_rqst can be changed during execution of notifiers and crash the host. Patch enables access to nlmsvc_rqst only when it was correctly initialized and delays its cleanup until notifiers are no longer in use. Note that nlmsvc_rqst can be temporally set to ERR_PTR, so the "if (nlmsvc_rqst)" check in notifiers is insufficient on its own.

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.
