Why do I see 'exe' as the process name in kernel panic backtraces?

Issue

• When investigating kernel backtraces generated within the kdump environment, the running process is unclear because it shows up as exe which is not an expected process name.

• For example:

  exe[15806]: segfault at ffffffffc0010062 rip 000000000052fc14 rsp 00007fff4fc4d5a8 error 6
