Re: [PATCH] Add rd.memdebug in kdump module

Description:
Currently we only added memdebug code before different dracut
hooks ie. pre-udev pre-pivot etc. Add memdebug in kdump.sh before
capturing vmcore is also good for debugging.
solution:
Add make_trace_mem before saving vmcore.
How much will we benefit from this while we've already got a debug point
at pre-pivot?
Thanks
