From a341d4df87487ae68189e0be869c39a2b0cb9aaa Mon Sep 17 00:00:00 2001 From: "Yan, Zheng" Date: Wed, 1 Jul 2015 17:03:23 +0800 Subject: [PATCH] ceph: invalidate dirty pages after forced umount After forced umount, ceph_writepages_start() skips flushing dirty pages. To make sure inode's reference count get dropped to zero, we need to invalidate dirty pages.
