In our world, requiring that sort of attention from maintainers requires a pretty active level of pinging, poking and harrassing ;) I do think that if you stick with get_random_bytes_arch() then it need a comment explaining why. And I (still) don't think that get_random_bytes_arch() actually does what you want - if CONFIG_ARCH_RANDOM isn't implemented then get_random_bytes_arch() just fails. IOW your statement "the arch version that will fallback on get_random_bytes sub API in the worse case" is a misconception? There is no fallback. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx. For more info on Linux MM, see: http://www.linux-mm.org/ .
