Subject: Re: [RESEND PATCH v7 00/10] Small-sized THP for anonymous memory
Date: Fri, 24 Nov 2023 10:02:10 +0100 [thread overview]
Message-ID: <659f0f6b-0fe2-4238-a6ae-5fd310c1a4ba@redhat.com> (raw)
In-Reply-To: <F516C7FB-3B40-421B-B0DA-E865806EE6B9@nvidia.com>
>> So we're really only concerned about:

>> * FileHugePages

>> The question is if we really want to continue extending/adjusting the old meminfo interfaces and talk about how to perform accounting there.

Yes!
