[Crash-utility] [PATCH 1/2] dis: Make the starting address of a function special for hexadecimal targets too
If no count is not entered, and the target address is the starting address
of a function, disassemble the entire function.
However this is only true, if the given target is symbolic.
This patch simply removes that restriction when the target is a hexadecimal
address:
For example, each of the following commands will return the same result.
- Where 0xffffffff80137e9d is assumed to be the address of the
first instruction in do_fork()
crash> dis 0xffffffff80137e9d
crash> dis do_fork
