Hi,

Here's a patch _idea_ to isolate anticipatory I/O from normal I/O
scheduler process by adding a specific put io context method so that
ll_rw_blk stuff could be as-iosched transparent.I guess we could point
as iosched exit instead of exit_io_context as well ...

Hi,
This makes ll_rw_blk.c aware of an AS specific function though.
as-iosched.c is actually a CONFIG option under CONFIG_EMBEDDED.
What is the actual problem?
