POSIX ACL support?

POSIX ACL support?

Is there POSIX ACL support in ceph?  If not, what needs to be done to
get it added?  I've set up a test system using Fedora 13 + a Rawhide
2.6.34.1-rc1 kernel, and copying files is working fine, but setting ACLs
gives me an "Operation not supported" error message.

Very little, I suspect, if all you want is ACL enforcement on the client 
side.  The xattr support is there, so I think some vfs hooks just need to 
be implemented.  I'm not too familiar with that part of the vfs, but I 
suspect most of the work is done by generic vfs helpers.
