readahead: MIN_RA_PAGES/MAX_RA_PAGES macros
Define two convenient macros for read-ahead:
- MAX_RA_PAGES: rounded down counterpart of VM_MAX_READAHEAD
- MIN_RA_PAGES: rounded _up_ counterpart of VM_MIN_READAHEAD
Note that the rounded up MIN_RA_PAGES will work flawlessly with _large_
page sizes like 64k.
