Cover letter [PATCH 0/3] prio_tree generalization
This patch set for 2.6.10-rc3-bk10 (*) generalizes the prio_tree code such that other subsystems than just VMA can use it.
(*) I'm not sure which tree is the most useful base for this.
Should I use 2.6.10-rc3-mm* instead of -bk* ? (Or is it already too late for 2.6.10 anyway ?)
While there are currently no other in-tree users than VMA, the prio_tree algorithm will be useful for detecting overlapping disk IO requests, which is a prerequisite for efficient handling of barriers, which - besides being a good idea in general - in turn is a prerequisite for useful disk IO priorities.
The three patches that follow are incremental and must be applied in the order specified.
