[PATCH] knfsd: nfsd4: handling more nfsd_cross_mnt errors in nfsd4 readdir

Browse Source 
This patch on its own causes no change in behavior, since nfsd_cross_mnt()
only returns -EAGAIN; but in the future I'd like it to also be able to return
-ETIMEDOUT, so we may as well handle any possible error here.
