Thanks Joe.

Joe, Shuah:

Could one of you please clarify if the changes proposed in the above URL 
will be part of Shuah's future patchset?

Or should I include those in my patchset? I am referring to the 
following snippet in security/integrity/integrity.h.


+#ifdef pr_fmt
+#undef pr_fmt
+#endif
+
+#define pr_fmt(fmt) KBUILD_MODNAME ": " KBUILD_BASENAME ": " fmt
+

If I add the above in my patchset, I believe I should remove #defines 
for pr_fmt in the .c files under /security/integrity? (except the below one)
latform_certs/efi_parser.c:#define pr_fmt(fmt) "EFI: "fmt

Please let me know.

Thanks,
Tushar
