grep -r KMOD_DECOMP_LEN ./linux-4.9.95
./linux-4.9.95/tools/perf/util/dso.c: char newpath[KMOD_DECOMP_LEN];

linux-4.9.95 still can't compile for tools/perf:

util/dso.c:370:16: error: 'KMOD_DECOMP_LEN' undeclared (first use in
this function)
make[3]: *** [util/dso.o] Error 1
make[2]: *** [util] Error 2
make[1]: *** [libperf-in.o] Error 2
make: *** [all] Error 2

Thanks.
