Subject: mon/OSDMonitor: use new style options
X-Git-Tag: v13.0.1~560^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=582e567c93f7656a1f3e16f473c583e6cb3d5926;p=ceph.git

mon/OSDMonitor: use new style options

* also mark "mon_osd_reporter_subtree_level" safe.
* change "mon_osd_min_down_reporters" to unsigned
* change "osd_pool_default_size" to unsigned
* change "osd_pool_default_min_size" to unsigned
* change "osd_pool_default_pg_num" to unsigned
* change "osd_pool_default_pgp_num" to unsigned
