[PATCH 00/11] cleanup/fix allow_signal/disallow_signal

[Oleg Nesterov]

Hello.

allow_signal() and disallow_signal() have the very strange (wrong
actually) semantics. They mix/confuse "sigprocmask" and "sigaction"
logic.

This series tries to cleanup and fix them, plus other (mostly related)
cleanups.

Oleg.
