[REVIEW][PATCH 18/22] signal/sparc: Use force_sig_fault where appropriate

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
