Subject: [PATCH 2/6] mm/page_alloc: Rename free_the_page() to free_frozen_pages()
Date: Tue, 31 May 2022 16:06:07 +0100	[thread overview]
Message-ID: <20220531150611.1303156-3-willy@infradead.org> (raw)
In-Reply-To: <20220531150611.1303156-1-willy@infradead.org>

In preparation for making this function available outside page_alloc,
rename it to free_frozen_pages(), which fits better with the other
memory allocation/free functions.
