Swap migration uses the two higest numbers of swap types (30 and 31). If those are generated by something then we could have trouble but I do not see how the patches could hurt otherwise.

ltp has many weird swap tests

(and I assume you're not talking about the pte's that are swapped, but
only the file type in the swap signature; since the higher bits in the
pte are used by the non-linear vma feature afaik)


How was the kernel compiled? It must have been running on a NUMA system for page migration to be enabled. Otherwise the fallback definitions in include/linux/swapops.h should remove all the swap migration entry handling.

x86_64 NUMA. Config is here:

mtest01 was what killed it, IIRC.
