In this patch, BIO_MAX_PAGES is changed from 256 to HPAGE_PMD_NR if
CONFIG_THP_SWAP is enabled and HPAGE_PMD_NR > 256. This is to support
THP (Transparent Huge Page) swap optimization. Where the THP will be
write to disk as a whole instead of HPAGE_PMD_NR

In this patch, BIO_MAX_PAGES is changed from 256 to HPAGE_PMD_NR if
CONFIG_THP_SWAP is enabled and HPAGE_PMD_NR > 256. This is to support
THP (Transparent Huge Page) swap optimization. Where the THP will be
write to disk as a whole instead of HPAGE_PMD_NR normal pages to batch
