    Subject[PATCH 0/9] oprofile: implement support of samples with variable data size
    Date
    This patch series implements support of samples with variable data
    size. Current implementation has a fixed sample size of 2 unsigned
    longs. This makes it hard to implement use cases with a different
    sample size (AMD IBS or power pc cell) since buffer locking is
    required or samples my become incomplete. The internal cpu buffer
    usage has been changed now and allows the attachment of data with
    varable length to samples.

    There are patches that also change the current ibs implementation. In
    the end the ibs implentation could be removed from the general
    oprofile code to model specific code. An API is available that
    provides generic functions to use variable sample sizes.

    The patches are also available here:
