Subject: [REVIEW][PATCH 18/22] signal/sparc: Use force_sig_fault where appropriate
Date: Fri, 20 Apr 2018 09:38:07 -0500 [thread overview]
Message-ID: <20180420143811.9994-18-ebiederm@xmission.com> (raw)
In-Reply-To: <87604mhrnb.fsf@xmission.com>
Filling in struct siginfo before calling force_sig_info a tedious and
error prone process, where once in a great while the wrong fields
are filled out, and siginfo has been inconsistently cleared.
Simplify this process by using the helper force_sig_fault. Which
takes as a parameters all of the information it needs, ensures
all of the fiddly bits of filling in struct siginfo are done properly
and then calls force_sig_info.
In short about a 5 line reduction in code for every time force_sig_info
is called, which makes the calling function clearer.
