This sounds very imprecise when you say "may not be enough". From what I understand you have already encountered systems where this is not enough so you have established that 45 seconds is too short. The next question is, how was 120 seconds determined and how do you know it will be enough?
It took about 68 seconds in my environment (Intel(R) Xeon(R) Gold 6254 CPU @ 3.10GHz). This test accesses a fixed size(250M) memory by default settings which is used when run in kselftest framework. I think that the execution time does not change significantly in different environments. So, I roughly doubled the execution time and get 120s, which I set to the limited time. I think it is enough for any environments. If 120s are also not enough, user can freely set the limited time by "setting" file.
Thanks for your feedback of this patch series, I will correct them in a few days.
