Subject: Re: [PATCH v7 0/5] Introduce provisioning primitives
Date: Thu, 18 May 2023 21:09:02 -0700 [thread overview]
Message-ID: <ZGb2Xi6O3i2pLam8@infradead.org> (raw)
In-Reply-To: <20230518223326.18744-1-sarthakkukreti@chromium.org>
FYI, I really don't think this primitive is a good idea. In the
concept of non-overwritable storage (NAND, SMR drives) the entire
concept of a one-shoot 'provisioning' that will guarantee later writes
are always possible is simply bogus.
