[Virtio-fs] [PATCH 0/2] virtiofsd: Add capability to block xattrs

[Vivek Goyal]

As of now we have a knob "-o xattr/no_xattr" which either enables
all xattrs or disables all xattrs.

We need something more fine grained where we can selectively disable
only certain xattrs (and not all).

For example, in some cases we want to disable "security.selinux"
xattr. This is equivalent to virtiofs not supporting security.selinux
and guest kernel will fallback to a single label for whole fs
(virtiofs_t).

So add an option "-o block_xattr=<list-of-xattrs>" which will allow
specifying a list of xattrs to block.

  virtiofsd: Add option "block_xattr=" to block certain xattrs
