I'm trying to redo my NFS RCU warning fixup patch on top of Paul's patches,
and I've found a small potential bug: nfs_inode_reclaim_delegation() doesn't
use the appropriate accessors/locks to protect NFS_I(inode)->delegation, and
nor does it use such to protect *delegation that I can see. It just
overwrites the record.
Furthermore, for consistency's sake, it should also protect accesses to
delegation->cred within that function.
Trond: can you confirm that both NFS_I(inode)->delegation and delegation->cred
should be considered RCU-protected pointers?
