[PATCH 1/2] mm/slab_common: add SLAB_NO_MERGE flag for use when creating slabs

2015-09-01 Thread Mike Snitzer
The slab aliasing/merging by default transition went unnoticed (at least to the DM subsystem). Add a new SLAB_NO_MERGE flag that allows individual slabs to be created without slab merging. This beats forcing all slabs to be created in this fashion by specifying sl[au]b_nomerge on the kernel
