lib/test_string.c: allow module removal

2021-07-01T18:06:05Z

The test_string module can't be removed because it lacks an exit hook. Since there is no reason for it to be permanent, add an empty one to allow module removal.

lib/test_string.c: add some testcases for strchr and strnchr

2019-07-17T02:23:22Z

Make sure that the trailing NUL is considered part of the string and can be found. Link: http://lkml.kernel.org/r/20190506124634.6807-4-peda@axentia.se Signed-off-by: Peter Rosin Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

lib/test_string.c: avoid masking memset16/32/64 failures

2019-07-17T02:23:22Z

If a memsetXX implementation is completely broken and fails in the first iteration, when i, j, and k are all zero, the failure is masked as zero is returned. Failing in the first iteration is perhaps the most likely failure, so this makes the tests pretty much useless. Avoid the situation by always setting a random unused bit in the result on failure.

lib: add module support to string tests

2017-11-18T00:10:01Z

Extract the string test code into its own source file, to allow compiling it either to a loadable module, or built into the kernel.
