Description

This issue was created by maloo for Andreas Dilger <[e-mail]>

This issue relates to the following test suite run: https://testing.whamcloud.com/test_sets/cbeb78f8-0978-11ea-bbc3-52540065bddc

test_60g failed with the following error:

usleep: command not found

It seems that "usleep" is a command specific to RHEL and does not exist in any package in Ubuntu. It is instead possible to replace "usleep 100" with "sleep 0.0001" (which is available in Ubuntu) to get the same effect (note overhead in calling sleep times this short is the same for both commands):

$ time for i in {0..1000}; do usleep 5000; done

real	0m7.732s
user	0m0.776s
sys	0m1.766s

$ time for i in {0..1000}; do sleep 0.005; done

real	0m7.888s
user	0m0.841s
sys	0m1.937s
