commit98af37d624upstream. In the fixes commit, removing SIGKILL from each thread signal mask and executing "goto fatal" directly will skip the call to "trace_signal_deliver". At this point, the delivery tracking of the SIGKILL signal will be inaccurate. Therefore, we need to add trace_signal_deliver before "goto fatal" after executing sigdelset. Note: SEND_SIG_NOINFO matches the fact that SIGKILL doesn't have any info.

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.
