Subject: Re: [PATCH] vmcore: convert mmap_vmcore_fault() to use folios
Date: Tue, 15 Sep 2026 23:53:41 +0000 [thread overview]
Message-ID: <20260915235342.507961F00893@smtp.kernel.org> (raw)
In-Reply-To: <20260915-vmcore-fault-folio-v1-1-a0cb6278670f@columbia.edu>
> Use a folio for the page cache page the s390 fault handler reads the
> old kernel's memory into. This removes four compound_head() calls and
> one of the last callers of find_or_create_page().
>
> The vmcore mapping only has order-0 folios, so the logic is unchanged.

> Compile tested for s390.
