Originally, calling ceph_get_fmode() for open files is by thread that handles request reply. There is a small window between updating caps and and waking the request initiator. We need to prevent ceph_check_caps() from releasing wanted caps in the window. Previous patches made fill_inode() call __ceph_touch_fmode() for open file requests. This prevented ceph_check_caps() from releasing wanted caps for 'caps_wanted_delay_min' seconds, enough for request initiator to get woken up and call ceph_get_fmode(). This allows us to now call ceph_get_fmode() in ceph_open() instead.
