From: "Dr. David Alan Gilbert" <dgilb...@redhat.com>
This is a second cut of a xattr name mapping option for virtiofsd.
It allows the user of virtiofsd to define a fairly flexible mapping
from the view of the xattr names the host fs has and the ones that the
guest sees.
The hope is this allows things like:
a) Different selinux attributes on host/guest
b) separation of trusted. attributes that clash on overlayfs
c) support for privileged xattr's in guests running with an
unprivileged virtiofsd.
There's no apparent standard for this kind of mapping, so I made
it flexible by specifying a mapping rule in the option.
Prefix's can be added (selectively or globally), xattr's can be
dropped in either direction or passed through.
