+
+ Linux 5.6 compat: ktime_get_raw_ts64()
+
+ The getrawmonotonic() and getrawmonotonic64() interfaces have been
+ fully retired. Update gethrtime() to use the replacement interface
+ ktime_get_raw_ts64() which was introduced in the 4.18 kernel.

+
+ Linux 5.6 compat: time_t
+
+ As part of the Linux kernel's y2038 changes the time_t type has been
+ fully retired. Callers are now required to use the time64_t type.
+
+ Rather than move to the new type, I've removed the few remaining
+ places where a time_t is used in the kernel code. They've been
+ replaced with a uint64_t which is already how ZFS internally
+ handled these values.
+
+ Going forward we should work towards updating the remaining user
+ space time_t consumers to the 64-bit interfaces.

+
+ 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.
