Trond Myklebust cfde64bd31 NFSv4: Fix races in the legacy idmapper upcall ... commit 51fd2eb52c upstream. nfs_idmap_instantiate() will cause the process that is waiting in request_key_with_auxdata() to wake up and exit. If there is a second process waiting for the idmap->idmap_mutex, then it may wake up and start a new call to request_key_with_auxdata(). If the call to idmap_pipe_downcall() from the first process has not yet finished calling nfs_idmap_complete_pipe_upcall_locked(), then we may end up triggering the WARN_ON_ONCE() in nfs_idmap_prepare_pipe_upcall(). The fix is to ensure that we clear idmap->idmap_upcall_data before calling nfs_idmap_instantiate().
