tools/vm/slabinfo: add option to sort by partial slabs
We would like to get a better view of the level of fragmentation within the SLUB allocator. Total number of partial slabs is an indicator of fragmentation. Add a command line option (-P | --partial) to sort the slab list by total number of partial slabs. Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Tobin C.
