Author: mmlr
Date: 2011-11-04 19:03:34 +0100 (Fri, 04 Nov 2011)
New Revision: 43188
Changeset: https://dev.haiku-os.org/changeset/43188
Added:
haiku/trunk/headers/private/kernel/AllocationTracking.h
Modified:
haiku/trunk/src/system/kernel/slab/slab_debug.h
Log:
Move AllocationTrackingInfo into a header. This way it can be re-used outside
of the slab code. It is generic as it only contains the link to a tracing entry
and not any application specific info.
Added: haiku/trunk/headers/private/kernel/AllocationTracking.h
