well for the expected workloads. Improvement in this commit include: - Added DEBUG_KMEM_TRACKING #define which can optionally be set when DEBUG_KMEM is defined to do per allocation tracking. This allows us to get all the lightweight kmem debugging enabled by default which is pretty light weight, and only when looking for a memory leak we can briefly enable the per alloc tracking. - Added set_normalized_timespec() in to SPL to simply using the timespec() primatives from within a module. - Added per-spinlock cycle counters to the slab in an attempt to run down a lock contention issue. The contended lock was in vmalloc() but I'm going to leave the cycle counters in place for a little while until I'm convinced there arn't other locking improvement possible in the slab. - Added a proc interface to the slab to export per slab cache statistics to /proc/spl/kmem/slab for analysis. - Reworked spl_slab_alloc() function to allocate from kmem for small allocation and vmem for large allocations. This improved things considerably but futher work is needed. git-svn-id: https://outreach.scidac.gov/svn/spl/trunk@138 7e1ea52c-4ff2-0310-8f11-9dd32ca42a1c |
