Dear Geert,
Sorry for writing you directory, but I saw you created the module
*string_selftest* in commit d6b28e09 (lib: add module support to string
tests).
I believe, I only did `make olddefconfig`, and the option is selected.
```
$ grep STRING_SELFTEST .config
CONFIG_STRING_SELFTEST=y
```
But booting with `initcall_debug` and looking at the systemd-bootchart
output in `/run/log`, doing this lasts 600 ms on my ASRock E350M1 with
Linux 4.16-rc5 (probably since the 4.15 cycle).
> string_selftest_init 636.2ms
If I didn’t do anything incorrectly, should the module be disable by
default?
Kind regards,
Paul

lib/Kconfig:
config STRING_SELFTEST
tristate "Test string functions"
In the absence of any "default" statement, the default is "n", so the module
should be already disabled by default.
