While debugging a problem recently with Alexander Leidinger we noticed
that crashinfo(8) was producing corrupt vmstat -m output. After doing
some digging it appears that memstat_kvm_malloc(3) might have been
broken by this commit:
The problem is that memstat_kvm_malloc(3) assumes that
malloc_type_internal starts with an array of malloc_types_stats
structures. This assumption is no longer true, though, as mti_probes
was inserted at the start of the structure.
It appears that this (untested) patch might fix the problem:
I'm not very familiar with dtrace, though. Does anyone know if this
would cause problems?
