Change the iomap ->page_prepare() handler to get and return a locked folio instead of doing that in iomap_write_begin(). This allows to recover from out-of-memory situations in ->page_prepare(), which eliminates the corresponding error handling code in iomap_write_begin(). The ->put_folio() handler now also isn't called with NULL as the folio value anymore. Filesystems are expected to use the iomap_get_folio() helper for getting locked folios in their ->page_prepare() handlers.
