is related to LU-9024 conf-sanity test_63: FAIL: ldisk inod... Resolved
Severity: 3
Rank (Obsolete): 9223372036854775807

 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?
