Subject: Re: [PATCH mm-unstable RFC v4 0/7] mm: add huge pfnmap support for remap_pfn_range()
Date: Tue, 26 May 2026 16:33:56 +0100	[thread overview]
Message-ID: <ahW7rut_WP17KADW@lucifer> (raw)
In-Reply-To: <20260526145003.88445-1-yintirui@huawei.com>

Allow me to be mildly pedantic (sorry :)

One thing I'd like to highlight here is that remap_pfn_range() is, in the long
run, deprecated.

mmap_prepare callbacks will indicate a PFN remap mmap_action, which will do the
heavy lifting (see [0]).

So perhaps worth referring to 'PFN remapping' or something?

(Since we already have mmap_prepare() in use, it's also kinda inaccurate to
say remap_pfn_range() :)

[0]: https://www.kernel.org/doc/html/next/filesystems/mmap_prepare.html

Sorry, this is pretty nitpicky :)

Cheers, Lorenzo
