would be fine to me. The problem isnt just distribution and the tests
getting out of sync with the kernel (and its capabilities enabled in the
.config, etc.), the other problem is unintrusive testing: i for example
use unmodified images of various distributions, with only a new bzImage
plopped in. That is an intentionally minimal impact test vector, any
userspace side changes are discouraged. And that's how many people test
new kernels, they just plop it in. The moment we require any userlevel
changes, the testing barrier increases significantly.
[ and a Friday rant: that's why the objection against my
make-relatime-actually-useful-to-people patch is so stupid,
shortsighted, self-defeating and misplaced. The "Dont put policy into
the kernel, use a new mount option and update your /etc/fstab"
stupidity that people have been repeating for 10 years without
thinking about it is a move that scares away 90% of our testers and
99% of the distros. See:
http://people.redhat.com/mingo/relatime-patches/improve-relatime.patch
Trivial improvement, it's 6 months and still not upstream. We are just
so good at shooting in our feet by creating artificial barriers and
making it as hard as possible for people to actually use our kernel
features ;-) ]
