= SYNOPSIS =
safe_cmd "<command>"

= DESCRIPTION =
This function is used to execute a command on the target with a greater
degree of safety. In particular, the oom score for the process is
adjusted so that if the target board runs out of memory during the execution, it will be the first process killed on the system.
|
|
It basically just calls ov_rootfs_oom to adjust
the oom score, and then calls cmd with the command to execute on target.

or disturbing other processes when executing the main command to execute the test.
