[Devel] [PATCH vz9 2/9] ve/sunrpc/nfsd: containerize kthreads

[Nikita Yushchenko]

From: Stanislav Kinsburskiy <skinsbursky at virtuozzo.com>

This patch set adds proper support for NFSd service in CT's, based on old
template (like RHEL6).
This patch allows to create NFSd kthreads to a containers pid namespace to
allow to stop the service on old distros (they send kill signals to NFSd
kernel threads).
