Andrew,
Here is one more adaptive readahead update.
It fixes:
- state based readahead
- thrashing recovery readahead
and cleanups:
- call scheme
- events/accounting
- rescue_pages()
Still in the todo list are:
- convert to Martin's statistic infrastructure
- a replacement of the stock readahead
to be simple, reliable and fast
Regards,
Fengguang Wu
