[Linux-cachefs] Does fs-cache work in conjunction with NFS4 + Kerberos?

Hi David,

thanks for the reply.

Sure, and it does look interesting:

NV SERVER   PORT USE HOSTNAME
v4 866406a5  801   6 rzfilesrv1
NV SERVER   PORT DEV     FSID              FSC
v4 866406a5  801 0:19    33:80             yes
v4 866406a5  801 0:20    d44824084a76c643  no 
v4 866406a5  801 0:21    14bba808365d2965  no 
v4 866406a5  801 0:22    c843f508f5e1b682  no 
v4 866406a5  801 0:23    ff8e0d0862a07886  no 
v4 866406a5  801 0:24    a512a90831bf9ec7  no 

More background: I am mounting a main directory from an OpenSolaris fileserver 
which transparently(?) automounts a large number if (per-user) ZFS partitions 
as subdirectories.

My first impression was that this was completely transparent to the NFS 
client, but I already learned that this is wrong, so my guess would be that 
the above 6 entries are 6 actual ZFS partitions on the server, only the first 
of which (the directly mounted one) gets cached?

Now the questions is why, or even better: Can we fix that? ;-)

Have a nice day,
