From 9bccb76574ad9ba6f5868b09053179fa2e72f8e0 Mon Sep 17 00:00:00 2001 From: "Yan, Zheng" Date: Tue, 10 Mar 2020 19:34:21 +0800 Subject: ceph: wait for async creating inode before requesting new max size ceph_check_caps() can't request new max size for async creating inode. This may make ceph_get_caps() loop busily until getting reply of the async create. Also, wait for async creating reply before calling ceph_renew_caps().
