Forget 200 lines, Red Hat speeds up Linux with 4 lines of code

[ Thanks to SMK for this link.

“From the ‘NO BS’ files:

“Speeding up Linux, doesn’t necessarily have to be a gargantuan
task and it doesn’t have to be done by Linus Torvalds either.

“On Monday, Torvalds praised a new 200 line Linux kernel patch
that was going to make Linux faster for all. Inside of the same
week, a new userspace patch has emerged that can likely do the same
thing, but with less code and even better performance.

“”I really wonder why logic like this should live in kernel
space at all,since a) the kernel has no real notion of a session,
except audit and b) this is policy and as soon as people have this
kind of group then they probably want other kind of autogrouping as
well for the other controllers, which hence means userspace is a
better, and configurable place for this.”Red Hat developer Lennart
Poettering wrote in a Linux Kernel Mailing list posting.”
