Subject: Checkpatch false positive?

Hello checkpatch.pl maintainers,

I'm adding a new thread flag and I get this apparent checkpatch false
positive:


ERROR: do not modify files in include/asm, change architecture specific files in include/asm-<architecture>
#36: +++ linux-2.6.27-rc1-mm1/arch/sparc/include/asm/thread_info_32.h

ERROR: do not modify files in include/asm, change architecture specific files in include/asm-<architecture>
#63: +++ linux-2.6.27-rc1-mm1/arch/sparc/include/asm/thread_info_64.h

ERROR: do not modify files in include/asm, change architecture specific files in include/asm-<architecture>

patches/0001-Container-Freezer-Add-TIF_FREEZE-flag-to-all-archit.patch total: 3 errors, 0 warnings, 214 lines checked

patches/0001-Container-Freezer-Add-TIF_FREEZE-flag-to-all-archit.patch has style problems, please review. If any of these errors
are false positives report them to the maintainer, see
CHECKPATCH in MAINTAINERS.


Which happens for every arch where the file has been moved under the
arch/ directory (sparc and parisc so far). Should this check for
arch/<foo>/include/asm before giving an ERROR? Should
arch/<foo>/include/asm only trigger a WARNING in this case?

Cheers,
-Matt Helsley

Yes, that check isn't very well anchored. I've tightened that up in the
latest version. Could you check your patch with the latest testing
version for me:
