From 204f6a8c413ec41a7ec5e3f0f0590d4318f7a1f2 Mon Sep 17 00:00:00 2001 From: Jiri Pirko Date: Thu, 7 Feb 2019 11:22:47 +0000 Subject: [PATCH] lib: objagg: add root count to stats Count number of roots and add it to stats. It is handy for the library user to have this stats available as it can act upon it without counting roots itself. Signed-off-by: Jiri Pirko Signed-off-by: Ido Schimmel Signed-off-by: David S.
