Subject: Re: [PATCH 17/20] bcache: support storing bcache journal into NVDIMM meta device
Date: Thu, 18 Feb 2021 21:21:00 +0000
Message-ID: <87k0r5ysw3.fsf@esperi.org.uk> (raw)
In-Reply-To: <20210210050742.31237-18-colyli@suse.de> (Coly Li's message of "Wed, 10 Feb 2021 13:07:39 +0800")

On 10 Feb 2021, Coly Li uttered the following:

> This patch implements two methods to store bcache journal to,
> 1) __journal_write_unlocked() for block interface device
>    The latency method to compose bio and issue the jset bio to cache

Is this really 'latency'? I suspect from other patches it should be
'legacy', which is surely not true unless the expectation is that soon
all bcache users will have NVDIMMs and can use the other path (surely
not).

> For lagency

This non-word should possibly be 'legacy' too?
