Subject: [PATCH 02/15] sched: change /proc/sched_debug fields
Date: Fri, 6 Sep 2019 15:12:24 -0400 [thread overview]
Message-ID: <20190906191237.27006-3-riel@surriel.com> (raw)
In-Reply-To: <20190906191237.27006-1-riel@surriel.com>
Remove some fields from /proc/sched_debug that are removed from
sched_entity in a subsequent patch, and add h_load, which comes in
very handy to debug CPU controller weight distribution.
