Subject: [RFC PATCH 5/5] signal: Remove the unnecessary restore_sigmask flag
Date: Fri, 07 Jun 2019 16:44:16 -0500 [thread overview]
Message-ID: <87pnnp9ikv.fsf_-_@xmission.com> (raw)
In-Reply-To: <87k1dxaxcl.fsf_-_@xmission.com> (Eric W. Biederman's message of "Fri, 07 Jun 2019 16:39:54 -0500")
__set_current_blocked already has a test to see if the new
value and the old value of the signal mask differ. Both
real_blocked and blocked should be on the same cache line,
and are a single word compare on 64bit.
Historically real_blocked or saved_sigmask could be garbage
so a test had to be used that always tested valid bits.
Now that real_blocked is alwasy valid there is no need
to test something different.
