Subject: Re: [RFC PATCH v11 0/5] blk-iocost: BPF struct_ops cost model
Date: Wed, 28 Oct 2026 10:09:25 -1000 [thread overview]
Message-ID: <07deddf44be391f58d6c3f2e4843582b@kernel.org> (raw)
In-Reply-To: <20261028143534.135968-1-cui.tao@linux.dev>
Hello, Tao.
Besides the restructuring agreed in my reply to Alexei, dropping
iocg_init()/iocg_free() and moving everything into blk-iocost.c, the
series still has problems, which I replied to on the patches. The cover
letter is still long and narrates mechanics, and it still carries the
v9 and v10 changelogs.
Thanks.
