Maybe I'm misreading your code but where do you check for multiple
pending signals?
It looks like you're handling only exact one signal before retuning to
userspace.
This is a serious issue, if you post a SIGSEGV i.e. in
do_rt_sigreturn() you need to handle it later
instead of directly returning to userspace.
