Subject: Re: [PATCH v3 1/5] kho: reject zero bootmem scale
Date: Thu, 12 Nov 2026 10:47:49 +0000 [thread overview]
Message-ID: <sashiko-outbox-210969@kernel.org> (raw)
In-Reply-To: <20261112-kho-bootmem-sizing-v3-1-f0c8d00295d5@kernel.org>
> kho_bootmem=0% sets bootmem_scale to 0, and then the bootmem areas are
> sized using the explicit sizes that default to 0. KHO remains enabled,
> but there is no usable bootmem to load the next kernel.
>
> Reject zero scale the same way zero explicit sizes are rejected.

> Fixes: 3dc92c311498 ("kexec: add Kexec HandOver (KHO) generation helpers")
