[for-next][PATCH 2/5] ktest: Fix child exit code processing

[Steven Rostedt]

From: "Steven Rostedt (VMware)" <rostedt@xxxxxxxxxxx>

The child_exit errno needs to be shifted by 8 bits to compare against the
return values for the bisect variables.

Fixes: c5dacb88f0a64 ("ktest: Allow overriding bisect test results")
