kernel-4.9.94 compile error: 'KMOD_DECOMP_LEN' undeclared

[Teck Choon Giam]

Hi,

Compile linux-4.9.94 will have error related to KMOD_DECOMP_LEN
undeclared.  Searching string related to KMOD_DECOMP_LEN in
linux-4.9.94 and linux-4.15.17 sources as below:

<mock-chroot>sh-4.2# grep -r KMOD_DECOMP_LEN ./linux-4.15.17
./linux-4.15.17/tools/perf/tests/code-reading.c: char
decomp_name[KMOD_DECOMP_LEN];
./linux-4.15.17/tools/perf/util/dso.h:#define KMOD_DECOMP_LEN
sizeof(KMOD_DECOMP_NAME)
./linux-4.15.17/tools/perf/util/annotate.c: char tmp[KMOD_DECOMP_LEN];
./linux-4.15.17/tools/perf/util/dso.c: char newpath[KMOD_DECOMP_LEN];
sh-4.2# grep -r KMOD_DECOMP_LEN ./linux-4.9.94
./linux-4.9.94/tools/perf/tests/code-reading.c: char
decomp_name[KMOD_DECOMP_LEN];
./linux-4.9.94/tools/perf/util/dso.c: char newpath[KMOD_DECOMP_LEN];

So I guess for linux-4.9.94 has not define KMOD_DECOMP_LEN in
tools/perf/util/dso.h?

Thanks.
