Subject: [PATCH 07/30] befs: Convert befs_symlink_read_folio() to use folio_end_read()
Date: Sat, 20 Apr 2024 03:50:02 +0100	[thread overview]
Message-ID: <20240420025029.2166544-8-willy@infradead.org> (raw)
In-Reply-To: <20240420025029.2166544-1-willy@infradead.org>

This is slightly more efficient than separate calls to
folio_mark_uptodate() and folio_unlock(), and it's easier to read.
Get rid of the call to folio_set_error() as nobody will check this flag.
