sys/amd64/linux/syscalls.master
458	Misplaced space, should be "struct pollfd *fds".
sys/compat/linux/linux_misc.c
2189	if (args->sset != NULL) {
2197	Why call SIGDELSET? A comment would be nice.
2201	if (args->tsp != NULL) {

Fixed, thanks! btw, also for all of Linuxulator's sigprocmask syscall family should be remove SIGKILL|SIGSTOP from new signal mask.
Will be fixed soon.

whoops, kern_sigprocmask() already call SIG_CANTMASK for new mask, so remove my SIGDELSET.
