    SubjectFile Corruption Bug.. continued
    I've now been through most of the 2.2.7->2.2.9 diff set discarding stuff
    that seems not to be a viable candiate.

    The remaining suspects are:
    o Quota - which has big 2.2.7->2.2.9 changes.
    o The small scsi changes (dubious)
    o A small mm change

    There are other candiates - notably
    TCP changes
    interrupt changes

    The tcp changes ought to have shown up more than this does. The interrupt
    changes dont really seem to explain cross platform stuff. And I doubt most
    people running these tests were running irda. NFS is a possibility.

    So - are most people seeing the problems running quotas ? And would someone
    with their brain firmly wrapped around the page cache/vfs verify this change
    that was made is absolutely safe
