Subject: [PATCH 1/3] jffs2: Pass the file pointer to jffs2_do_readpage_unlock()
Date:   Mon,  2 May 2022 06:41:57 +0100
Message-Id: <20220502054159.3471078-2-willy@infradead.org>

In preparation for unifying the read_cache_page() and read_folio()
implementations, make jffs2_do_readpage_unlock() get the inode
from the page instead of passing it in from read_cache_page().
