Subject: Re: [PATCH 04/19] staging: lustre: discard cfs_time_seconds()
> cfs_time_seconds() converts a number of seconds to the

> The standard way to do this in Linux is "* HZ".
> So discard cfs_time_seconds() and use "* HZ" instead.
Just to make you aware I have been working for several months on
moving lustre away from using jiffies as much as possible. The
problem with using HZ is that it can vary. So when you have a
parallel file system with batches of nodes that have different
values of HZ you can get very interesting corner cases. So I have
been moving everything over to time64_t and ktime. Also I mostly
have killed off the cfs_time_shift* and crap as well. You see all
work under https://jira.hpdd.intel.com/browse/LU-9019. So many
of the cases you did below don't event exist any more. I was
planning to push those changes after the next merge window.
