Subject: linux-next: build failure after merge of the nfsd tree

Hi all,

After merging the nfsd tree, today's linux-next build (x86_64
allmodconfig) failed like this:

fs/nfsd/nfs4proc.c: In function 'nfsd4_getdeviceinfo_release':
fs/nfsd/nfs4proc.c:1356:8: error: 'gdev' undeclared (first use in this function)
  kfree(gdev->gd_device);
        ^
fs/nfsd/nfs4proc.c:1356:8: note: each undeclared identifier is reported only once for each function it appears in
fs/nfsd/nfs4proc.c: At top level:

fs/nfsd/nfs4proc.c: In function 'nfsd4_layoutget_release':
fs/nfsd/nfs4proc.c:1441:8: error: 'lgp' undeclared (first use in this function)
  kfree(lgp->lg_content);
        ^

fs/nfsd/nfs4proc.c:1442:1: warning: control reaches end of non-void function [-Wreturn-type]
 }
 ^

Caused by commit

  93e92e5d0016 ("nfsd4: define ->op_release for compound ops")

I have used the nfsd tree from next-20170824 for today.
