[lustre-devel] [PATCH 0/8] staging: lustre: lnet: resolve time handling issues

[James Simmons]

The migration of lustre to 64 bit time handling exposed various bugs
which have lead to problems like routers no longer functioning with
the upstream client. This is due to the complex handling of time by
lustre with seconds time units and jiffies. Add in the fact that
jiffies can vary from node to node and you can encounter corner
case issues in a large node deployment. The solution to resolve this
was to migrate as much as possible to time64_t when all you needed
was seconds percision and ktime_t if better percision was required.
With these changes it is reduced down to using jiffies only for
schedule_timeout calls.

James Simmons (8):
