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

xxhdx1985126 · xxhdx1985126 · commit 8495d64e3339 · 2025-08-25T07:13:58.000Z
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. Fixes: https://tracker.ceph.com/issues/72701 Signed-off-by: Xuehan Xu <xuxuehan@qianxin.com>
