From 4a1e2feb9d246775dee0f78ed5b18826bae2b1c5 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Sun, 30 Aug 2015 18:37:59 -0700 Subject: [PATCH] NFSv4.1: Fix a protocol issue with CLOSE stateids According to RFC5661 Section 18.2.4, CLOSE is supposed to return the zero stateid. This means that nfs_clear_open_stateid_locked() cannot assume that the result stateid will always match the 'other' field of the existing open stateid when trying to determine a race with a parallel OPEN. Instead, we look at the argument, and check for matches. Cc: stable@vger.kernel.org # v4.0+ Signed-off-by: Trond Myklebust --- Reading git-format-patch failed
