Subject: mds-client: make the fake inos option unchangeable in runtime
X-Git-Tag: v17.2.4~72^2~4
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=61fbc9a273af9d7ef91056e0f4fcc2a09e5cd559;p=ceph.git

mds-client: make the fake inos option unchangeable in runtime

If the flags is empty then in option.h in can_update_at_runtime()
it will return true. That means this opetion could be changed in
runtime, which is buggy. Because if this is false, ceph-fuse will
use its own fake inos instead of libcephfs'. If this is changed
during runtime, we will hit inos dosn't exist assert bugs.
