It's also just a test module though so the code isn't particularly crucial. Herbert/David? thoughts?

Please read the function as a whole, that fallthrough (and every other one in do_test) needs to stay. Thanks,

I saw some continue uses as well but wasn't sure and didn't look to see if the switch/case with continue was in a for/while loop.

Hi Herbert. OK, I did. I think it's odd code. The do_test function could start at any 3xx or 4xx mode and then do all the next tests to the highest 99 for ranges from 301-399 and 401-499. ie: Pass mode 312, it'll execute test 312 and every other test to 399. Not the same for the 500-599 or 600-699 range. I probably would've hoisted the code for all of the 0, any value from 300-399, and any value from 400-499 out of the do_test function and into tcrypt_mod_init not used fallthrough in do_test at all. cheers, Joe Perhaps something like: --- crypto/tcrypt.c | 190 +++++++++++++++++++++----------------------------------- 1 file changed, 72 insertions(+), 118 deletions(-) diff --git a/crypto/tcrypt.c b/crypto/tcrypt.c index eea0f453cfb6..aeb089f6ee27 100644 --- a/crypto/tcrypt.c +++ b/crypto/tcrypt.c @@ -1660,7 +1660,6 @@ static inline int tcrypt_test(const char *alg) static int do_test(const char *alg, u32 type, u32 mask, int m, u32 num_mb) { - int i;

The code is more complex with multiple 'fallthrough', so this change alone actually makes the code inconsistent. A rework would need a seperate patch.
Joe, Please drop this chunk: it's a successive controller version number which are all backward compatible with "fallthrough" on each case so removing from this last one makes it inconsistent.

It just happens that anything we would do for the common subset is implicitly assumed (there are other potential cases we simply haven't added support for at the moment), thus the second case is currently empty. This change actively obfuscates that distinction. Robin.
