+commit 795699a6cc28b8f1059397e03d1a86d576bfc7dc
+Author: Brian Behlendorf <behlendorf1@llnl.gov>
+Date: Thu Feb 6 12:37:25 2020 -0800
+
+ Linux 5.6 compat: timestamp_truncate()
+
+ The timestamp_truncate() function was added, it replaces the existing
+ timespec64_trunc() function. This change renames our wrapper function
+ to be consistent with the upstream name and updates the compatibility
+ code for older kernels accordingly.
+
+ Reviewed-by: Tony Hutter <hutter2@llnl.gov>
+ Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov>
+ Closes #9956
+ Closes #9961
