Powertop keeps indicating that I should enable CONFIG_INOTIFY option. But I am having difficulty finding it. Search indicates that it lives here:

Quote:
Symbol: INOTIFY_USER [=y] │
│ Type : boolean │
│ Prompt: Inotify support for userspace │
│ Defined at fs/notify/inotify/Kconfig:1 │
│ Location: │
│ (1) -> File systems │
│ Selects: ANON_INODES [=y] && FSNOTIFY [=y]


But I don't see it under File System at all. Am I missing something?

That is INOTIFY_USER, not INOTIFY. I do not see that option in recent kernel configuration options. How exactly is powertop indicating that this feature is missing?

Whoops. Yes that is correct. When I searched for INOTIFY_USER that is the only option it returns and like you I don't see it in the kernel options.

Powertop kicks this out:

Quote:
Enable the CONFIG_INOTIFY kernel configuration option.
This option allows programs to wait for changes in files and directories
instead of having to poll for these changes

It looks like the text of that advice is outdated. Enabling INOTIFY_USER satisfies the intent of the advice, though not its literal text.

Should I report this as a bug and if so where? Gentoo? Powertop?

Yes. As I understand your posts, it sounds like the bad message is from Powertop itself, so report it to the Powertop authors.
