Subject: crimson/os/seastore/cache: clear extents_index when the booting is done
X-Git-Url: http://git.apps.os.sepia.ceph.com/?a=commitdiff_plain;h=8495d64e3339eb97c4c04b826fb3ad29aeabe41c;p=ceph.git

crimson/os/seastore/cache: clear extents_index when the booting is done

Since all extents including RetiredExtentPlaceholder are linked to lba
leaf nodes, Cache::extents_index is only useful to link all lba/backref
nodes and logical extents together before SeaStore is fully booted.

So we should clear Cache::extents_index after SeaStore is booted.
