The description of PR_SET_PDEATHSIG refers to "maxsig", which is apparently intended to stand for the maximum defined signal number. maxsig seems not to be a thing, even in the kernel. Reword to use the standard constant NSIG. (Discussion of SIGRTMIN and SIGRTMAX seems out of scope here, and anyway is not relevant to the kernel.)
