.`makedumpfile` now includes improved options to get an estimated `vmcore` size
With this implementation, the `makedumpfile` utility now includes the following options which help to print an estimate for the dump size for the currently running kernel:
* `--dry-run` performs all operations specified by the other options but does not write the output file.
* `--show-stats` prints the report messages. This is an alternative to enabling bit 4 in the level provided to `--message-level` option.
The following example shows the `--dry-run` and `--show-stats` usage:
----
$ makedumpfile --dry-run --show-stats -l --message-level 7 -d 31 /proc/kcore dump.dummy
----
Note that the dump file size may vary depending on the system state at the time of panic and the estimate provided by the options may differ from the actual state.
