From 576163005de286bbd418fcb99cfd0971523a0c6d Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Wed, 10 Aug 2011 19:16:22 -0400 Subject: [PATCH] nfsd4: fix seqid_mutating_error The set of errors here does *not* agree with the set of errors specified in the rfc! While we're there, turn this macros into a function, for the usual reasons, and move it to the one place where it's actually used. Cc: stable@kernel.org Signed-off-by: J.
