NFS: struct nfs_commit_info.lock must always point to inode->i_lock
Commit 411a99adffb4f (nfs: clear_request_commit while holding i_lock) assumes that the nfs_commit_info always points to the inode->i_lock. For historical reasons, that is not the case for O_DIRECT writes. Cc: Weston Andros Adamson <dros@primarydata.com> Fixes: 411a99adffb4f ("nfs: clear_request_commit while holding i_lock") Cc: stable@vger.kernel.org # 3.17.x Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>
