Subject: Re: [PATCH v4 00/16] block: add blktrace support for zoned block devies
Date: Mon, 20 Oct 2025 22:25:23 -0400 [thread overview]
Message-ID: <yq14irt6lfk.fsf@ca-mkp.ca.oracle.com> (raw)
In-Reply-To: <20251020134123.119058-1-johannes.thumshirn@wdc.com> (Johannes Thumshirn's message of "Mon, 20 Oct 2025 15:41:07 +0200")
Johannes,
> This patch series extends the kernel blktrace infrastructure to

Looks OK to me.
