Subject: [PATCH] kho: fix doc for kho_restore_pages()
Date: Fri, 23 Jan 2026 12:05:06 -0700 [thread overview]
Message-ID: <20260123190506.1058669-1-tycho@kernel.org> (raw)
From: "Tycho Andersen (AMD)" <tycho@kernel.org>
This function returns NULL if kho_restore_page() returns NULL, which
happens in a couple of corner cases. It never returns an error code.
Signed-off-by: Tycho Andersen (AMD) <tycho@kernel.org>
