checkpatch: add __ro_after_init to known $Attribute
__ro_after_init is a specific __attribute__ that checkpatch does currently not understand. Add it to the known $Attribute types so that code that uses variables declared with __ro_after_init are not thought to be a modifier type. This appears as a defect in checkpatch output of code like: static bool trust_cpu __ro_after_init = IS_ENABLED(CONFIG_RANDOM_TRUST_CPU); [...] if (trust_cpu && arch_init) { where checkpatch reports: ERROR: space prohibited after that '&&' (ctx:WxW) if (trust_cpu && arch_init) { Link: http://lkml.kernel.org/r/0fa8a2cb83ade4c525e18261ecf6cfede3015983.camel@perches.com Signed-off-by: Joe Perches <joe@perches.com> Reported-by: Kees Cook <keescook@chromium.org> Tested-by: Kees Cook <keescook@chromium.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
