[PATCH 0/3] lib/string: search for NUL with strchr/strnchr

From: Peter Rosin

I noticed an inconsistency where strchr and strnchr do not behave the
same with respect to the trailing NUL. strchr is standardised and the
kernel function conforms, and the kernel relies on the behavior.
So, naturally strchr stays as-is and strnchr is what I change.

While writing a few tests to verify that my new strnchr loop was sane, I
noticed that the tests for memset16/32/64 had a problem. Since it's all
about the lib/string.c file I made a short series of it all...

But where to send it? get_maintainer suggests no victim, so I'm aiming
at those that signed-off on the memset16/32/64 bug...


Peter Rosin (3):
lib/string: allow searching for NUL with strnchr
lib/test_string: avoid masking memset16/32/64 failures
lib/test_string: add some testcases for strchr and strnchr
