[PATCH 2/4] f2fs: fix debugfs status to reflect the online resize changes

From: Sahitya Tummala
Date: Tue Apr 09 2019 - 06:36:52 EST


The main area segs/secs/zones will be updated/changed after an
online resize. Hence, update the struct f2fs_stat_info as well
accordingly to show correct status in debugfs.
