NO_HZ_LEAVE_ME_THE_FSCK_ALONE!

NO_HZ_OVERFLOWING?

Actually, "NO_HZ" shouldn't appear in the name at all.  The objective
is to permit userspace to execute without interruption.  NO_HZ is a
part of that, as is NO_INTERRUPTS.  The "NO_HZ" thing is a historical
artifact from an early partial implementation.

Agreed! Which is why I'd rather advocate in favour of CONFIG_ISOLATION.

Then we should have CONFIG_LEAVE_ME_THE_FSCK_ALONE. Hmm, I guess that's
just an synonym for CONFIG_ISOLATION.
