Subject: [PATCH v1 00/20] signal: refactor some functions
Hey,
This series refactors a bunch of functions in signal.c to simplify parts
of the code.
The greatest single change is declaring the static do_sigpending()
helper as void which makes it possible to remove a bunch of unnecessary
checks in the syscalls later on.
Thanks!
Christian
