Subject: Re: [PATCH v2 3/3] dics/memory-barriers.txt/kokr: Allow architecture to override the flush barrier
Date: Sat, 29 Aug 2020 10:38:19 +0200 [thread overview]
Message-ID: <20200829083819.4350-1-sj38.park@gmail.com> (raw)
In-Reply-To: <20200829082607.3146-4-sj38.park@gmail.com>
Ah, why I always see the typo only after posting it... The title should start
with 'docs/', not 'dics/'. Sorry, I will send a fixed patch as reply to this.
If you want full v3 patchset, just let me know, please.
Thanks,
SeongJae Park
