ceph: EIO all operations after forced umount
This patch makes try_get_cap_refs() and __do_request() check if the file system was forced umount, and return -EIO if it was. This patch also adds a helper function to drops dirty caps and wakes up blocking operation. Signed-off-by: Yan, Zheng <zyan@redhat.com>
