Subject: [PATCH 2/8] sched: change /proc/sched_debug fields
Date: Wed, 12 Jun 2019 15:32:21 -0400 [thread overview]
Message-ID: <20190612193227.993-3-riel@surriel.com> (raw)
In-Reply-To: <20190612193227.993-1-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.
