Subject: nfs: Fix "Don't increment lock sequence ID after NFS4ERR_MOVED"
From: Chuck Lever <chuck.lever@xxxxxxxxxx>
[ Upstream commit 406dab8450ec76eca88a1af2fc15d18a2b36ca49 ]
Lock sequence IDs are bumped in decode_lock by calling
nfs_increment_seqid(). nfs_increment_sequid() does not use the
seqid_mutating_err() function fixed in commit 059aa7348241 ("Don't
increment lock sequence ID after NFS4ERR_MOVED").
Fixes: 059aa7348241 ("Don't increment lock sequence ID after ...")
