iomap: move bio read logic into helper function

Browse source

Move the iomap_readpage_iter() bio read logic into a separate helper
function, iomap_bio_read_folio_range(). This is needed to make iomap
read/readahead more generically usable, especially for filesystems that
do not require CONFIG_BLOCK.

Additionally rename buffered write's iomap_read_folio_range() function
to iomap_bio_read_folio_range_sync() to better describe its synchronous
behavior.
