From 0989a7889695831e49e2c53c1884f52645516a90 Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Tue, 17 Jul 2007 04:04:44 -0700 Subject: knfsd: nfsd: provide export lookup wrappers which take a svc_rqst Split the callers of exp_get_by_name(), exp_find(), and exp_parent() into those that are processing requests and those that are doing other stuff (like looking up filehandles for mountd). No change in behavior, just a (fairly pointless, on its own) cleanup. (Note this has the effect of making nfsd_cross_mnt() pass rqstp->rq_client instead of exp->ex_client into exp_find_by_name(). However, the two should have the same value at this point.) Signed-off-by: "J.
