Subject: Modify gethrestime to use current_kernel_time()
X-Git-Tag: spl-0.6.2~8
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=c47efbc7fda5eaed9b60b3767347d9f88553309b;p=spl

Modify gethrestime to use current_kernel_time()

This allows us to get nanosecond resolution. It also means
we use the same time source as utimensat(now) etc.
