Subject: NFS: rewrite nfs_delegations_present in terms of nr_active_delegations
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2d80e59f29d8cd14230899dfe9c462b710521a85;p=thirdparty%2Fkernel%2Flinux.git

NFS: rewrite nfs_delegations_present in terms of nr_active_delegations

Renewal only cares for active delegations and not revoked ones.  Replace
the list empty check with reading the active delegation counter to
implement this.
