Qun-Wei Lin 0258c527fb FROMLIST: mm: Split SWP_SYNCHRONOUS_IO into separate read and write flags ...

This patch splits the SWP_SYNCHRONOUS_IO flag into __SWP_READ_SYNCHRONOUS_IO
and __SWP_WRITE_SYNCHRONOUS_IO.

These changes are motivated by the need to better accommodate certain
swap devices that support synchronous read operations but asynchronous write
operations.

The existing SWP_SYNCHRONOUS_IO flag is not sufficient for these devices,
as they enforce synchronous behavior for both read and write operations.
