After the emergency slab objects were merged I started observing timeout failures in the kmem:slab_overcommit test. These were due to the ineffecient way the slab_overcommit reclaim function was implemented. And due to the additional cost of potentially allocating ten of thousands of emergency objects and tracking them on a single list. This patch addresses the first concern by enhansing the test case to trace all of the allocations objects as a linked list. This allows for a cleaner version of the reclaim function to simply release SPLAT_KMEM_OBJ_RECLAIM objects. Since this touches some common code all the tests which share these data structions were also updated. After making these changes slab_overcommit is reliably passing. However, there is certainly additional cleanup which could be done here. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> |
