The use of timerfd will impact the minimum OS version, have you
checked this is OK? Does RHEL5 still work?
It was added in linux v2.6.25. I think that an API that's more than
6.5 years old is valid.
RHEL5 is using 2.6.18 as their base kernel. You should at least
consult with the OFED people to determine if this is a problem for
them.
Please don't. This code should not be changed for something as ancient as rhel5.
Indeed. Telling people to avoid using constructs/mechanisms ~6-7 years
after they were introduced isn't something we want nor need to do.
Or.
