Coleman Kane c0fb44c506 Linux 5.16: wait_on_page_bit() no longer available to modules ... Instead, linux/pagemap.h offers a number of folio-specific functions to be called instead. In this case, module/os/linux/zfs/zfs_vnops_os.c wants to call wait_on_page_bit(pp, PG_writeback). This gets replaced with folio_wait_bit(folio_page(pp), PG_writeback). This change modifies the code to conditionally compile that if configure identifies th presence of the folio_wait_bit() function.
