...dows, which has a DeviceIOControl called FSCTL_QUERY_ALLOCATED_RANGES that returns an array of offset and length values, within a given range in a file (also specified by offset and length). So, it?s almost a direct mapping to the extension I proposed. I basically have three different versions of a request_ranges() function (Windows, systems with SEEK_DATA/SEEK_HOLE, and a dummy implementation for all other platforms which just returns the full range passed in). The risk of missing data due to file changes is no different than what could happen if you were reading data sequentially and something did a wri...

...on NO_HZ and using the proper clockevents infrastructure. I am looking for feedback on this, but it works and applies as is, and is certainly better and cleaner than the existing code. Hopefully I have taken as many fingers out of the APIC pie as possible. Finally, fix the BusLogic driver to use request_range properly. Zach
