The two patches you posted are related. Please group them as a patch
set, making this patch 2/2.
In addition, as Shuah Khan suggested for the security/integrity/
directory, "there is an opportunity here to add #define pr_fmt(fmt)
KBUILD_MODNAME ": " fmt to integrity.h and get rid of duplicate
defines." With Joe Perches patch (waiting for it to be re-posted),
are all the pr_fmt definitions needed in each file in the
integrity/ima directory?

There's no reason to split the statement like this. The joined line
is less than 80 characters.
