From d4395e03fec0895d01451904b8a2276ceda663c9 Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Fri, 26 Oct 2007 13:32:50 -0400 Subject: knfsd: fix broken length check in nfs4idmap.c Obviously at some point we thought "error" represented the length when positive. This appears to be a long-standing typo. Thanks to Prasad Potluri for finding the problem and proposing an earlier version of this patch. Cc: Steve French Cc: Prasad V Potluri Signed-off-by: J.
