From: Anatoly Pugachev <matorola@gmail.com>
[ Upstream commit cae1d5a2c5a491141faa747e9944ba40ab4ab786 ]
When running gup_benchmark test the following output states that the config options is missing.
$ sudo ./gup_benchmark open: No such file or directory
$ sudo strace -e trace=file ./gup_benchmark 2>&1 | tail -3 openat(AT_FDCWD, "/sys/kernel/debug/gup_benchmark", O_RDWR) = -1 ENOENT (No such file or directory) open: No such file or directory +++ exited with 1 +++
Fix it by adding config option fragment.
