[LU-12030] rhel7.6 removed kmalloc-128 slab causing conf-sanity test_63 to fail on DEBUG_SLAB kernels

• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.13.0, Lustre 2.12.5
• Severity: 3
• Assignee: Oleg Drokin
• Reporter: Oleg Drokin

Description

our detection of debug kernels broke because of that kmalloc-128 slab removal.  This causes conf-sanity test_63 to fail with:

conf-sanity2@ldiskfs+DNE Failure(6341s)
- 63(ldiskfs inode too big, only 1 objs/page,  kmalloc128 =  objs/page)  

So let's use dma-kmalloc-128 that seems to be universally present?
