Description

Adding some support for POSIX_FADV_WILLNEED to schedule read-ahead. I have various patches to do this on UFS. The naive version only triggered 16k reads. I tried hacking up the clustering code to allow these to cluster but that was quite complex and still hard to get correct, so I think it is worth dropping.
