Subject: [patch 080/163] tools/cgroup: add memcg_slabinfo.py tool
Date: Thu, 06 Aug 2020 23:21:34 -0700 [thread overview]
Message-ID: <20200807062134.HxAtzPcM2%akpm@linux-foundation.org> (raw)
In-Reply-To: <20200806231643.a2711a608dd0f18bff2caf2b@linux-foundation.org>

Subject: tools/cgroup: add memcg_slabinfo.py tool
Add a drgn-based tool to display slab information for a given memcg. Can
replace cgroup v1 memory.kmem.slabinfo interface on cgroup v2, but in a
more flexiable way.
Currently supports only SLUB configuration, but SLAB can be trivially
added later.
Output example:
