From 7aa262b522ee5a7f1bf9b8fe34539b262ba6da0a Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Thu, 28 Feb 2013 16:19:59 -0800 Subject: [PATCH] NFSv4: Fix another open/open_recovery deadlock If we don't release the open seqid before we wait for state recovery, then we may end up deadlocking the state recovery thread. This patch addresses a new deadlock that was introduced by commit c21443c2c792cd9b463646d982b0fe48aa6feb0f (NFSv4: Fix a reboot recovery race when opening a file) Reported-by: Andy Adamson Signed-off-by: Trond Myklebust --- fs/nfs/nfs4proc.c | 1 + 1 file changed, 1 insertion(+) diff --git a/fs/nfs/nfs4proc.c b/fs/nfs/nfs4proc.c index 655237f..37eb385 100644 --- a/fs/nfs/nfs4proc.c +++ b/fs/nfs/nfs4proc.c @@ -1158,6 +1158,7 @@ _nfs4_opendata_to_nfs4_state(struct nfs4_opendata *data) data->o_arg.fmode); iput(inode); out: + nfs_release_seqid(data->o_arg.seqid); return state; err_put_inode: iput(inode); -- 2.7.4
