[LTP] [PATCH V2 3/3] syscalls: sigwait: Separate out code to relevant folders
Viresh Kumar
viresh.kumar@linaro.org
Tue Jul 21 10:52:04 CEST 2020
The way it is implemented currently is very confusing, all the source
code is present in one file which is referenced from 4 directories to
test different syscalls. The relevant source gets build magically based
on some flag passed in Makefile.
Move the common part to a new library and the relevant part to their
syscall folders.
