From 416dfc70ef87400e1ddfd70e5b6e512d330b54a6 Mon Sep 17 00:00:00 2001 From: Sheetal Pamecha Date: Tue, 2 Apr 2019 23:25:11 +0530 Subject: [PATCH 43/52] inode: don't dump the whole table to CLI dumping the whole inode table detail to screen doesn't solve any purpose. We should be getting only toplevel details on CLI, and then if one wants to debug further, then they need to get to 'statedump' to get full details.
