Subject[RFC 05/26] SLUB: Replace ctor field with ops field in /sys/slab/:0000008 /sys/slab/:0000016 /sys/slab/:0000024 /sys/slab/:0000032 /sys/slab/:0000040 /sys/slab/:0000048 /sys/slab/:0000056 /sys/slab/:0000064 /sys/slab/:0000072 /sys/slab/:0000080 /sys/slab
Create an ops field in /sys/slab/*/ops to contain all the operations defined
on a slab. This will be used to display the additional operations that we
will define soon.
