commit 2c3a83701dd185cadb30db4556256534e2930c7d

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.
