From 8692969e9164c15474b356b9898e5b9b21a85643 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Mon, 6 Jun 2022 19:31:42 -0400 Subject: ceph: wait on async create before checking caps for syncfs Currently, we'll call ceph_check_caps, but if we're still waiting on the reply, we'll end up spinning around on the same inode in flush_dirty_session_caps. Wait for the async create reply before flushing caps.
