scripts/decode_stacktrace.sh: guess path to vmlinux by release name
Add option decode_stacktrace -r <release> to specify only release name.
This is enough to guess standard paths to vmlinux and modules:
$ echo -e 'schedule+0x0/0x0
tap_open+0x0/0x0 [tap]' |
./scripts/decode_stacktrace.sh -r 5.4.0-37-generic
schedule (kernel/sched/core.c:4138)
tap_open (drivers/net/tap.c:502) tap
