Subject: mm/kfence: use special gfp_t format specifier
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d36102a5f55321b9bdf3e40fbb7b5c482e6dfb12;p=thirdparty%2Fkernel%2Fstable.git

mm/kfence: use special gfp_t format specifier

%pGg produces nice readable output and decouples the format string from
the size of gfp_t.
