I was looking for self-test code to emulate for lib/glob.c and, while canvassing other code with self-tests, found some code that made me itch, so I scratched it.
7 patches; 1/7: Mark the self-test data as __initconst 2/7: Remove excess calls to prandom_u32_state in initialization 3/7: Replace an #ifdef with a stub prandom_state_selftest() 4/7: Use <asm/unaligned.h> instead of hand-rolling it 5/7: Make prandom_u32_max efficient for powers of 2 6/7: Randomize timeout to the millisecond, not the second 7/7: Remove redundant U suffixes on integers I have a big follow-on patch series to replace all the (many) instances of "prandom_u32() % x" in the kernel with prandom_u32_max(x), which is more efficient. As of patch 5/7, "prandom_u32() & (x-1)" can also be replaced by "prandom_u32_max(x)", but that's optional. Patch 6/7 is dubious, and I'd like comments. I just don't see a reason why integer granularity would be desirable. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
