From 231817ee68a9640d91ef34ce12c4d67b38f17ed8 Mon Sep 17 00:00:00 2001 From: Weston Andros Adamson Date: Mon, 21 Oct 2013 13:10:13 -0400 Subject: [PATCH] NFSv4: don't reprocess cached open CLAIM_PREVIOUS commit d2bfda2e7aa036f90ccea610a657064b1e267913 upstream. Cached opens have already been handled by _nfs4_opendata_reclaim_to_nfs4_state and can safely skip being reprocessed, but must still call update_open_stateid to make sure that all active fmodes are recovered.
