Subject: [PATCH 0/3] kthread: pass in user and check RLIMIT_NPROC

The vhost driver will create a kthread when userspace does a
VHOST_SET_OWNER ioctl, but the thread is charged to the kthreadd thread.
We can then end up violating the userspace process's RLIMIT_NPROC. This
patchset allows drivers to pass in the user to charge/check.

The patches were made over Linus's current tree.
