    Subject[patch 0/6] Linux Kernel Markers
    Hi,

    The Linux Kernel Markers have been reworked to now depend on the "Conditional
    Calls" as a basic infrastructure for enabling the calls to the function
    pointers (probes).

    The second major change in this release is the use of a hash table to keep track
    of the enabled markers : it permits it issue the marker_arm_probe before loading
    a module containing the specified probe. The probe connexion to the marker is
    done both when the marker is armed and at module load time. It fixes an
    unexpected behavior of the previous version, which was due to the fact that
    users might have expected that the markers would be set for newly loaded
    modules. Since there is no dependency between the marker and modules, the order
    could easily be wrong.

    A hash table using a hash of the marker name is used to give O(1) lookup at
    module load time.

    This serie of patches depends on the conditional calls. Please add at the end of
    the 2.6.22-mm1 series:
