4Subject: [PATCH] Linux 5.6 compat: struct proc_ops
5
6The proc_ops structure was introduced to replace the use of of the
7file_operations structure when registering proc handlers. This
8change creates a new kstat_proc_op_t typedef for compatibility
9which can be used to pass around the correct structure.
10
11This change additionally adds the 'const' keyword to all of the
12existing proc operations structures.

256Subject: [PATCH] Linux 5.6 compat: timestamp_truncate()
257
258The timestamp_truncate() function was added, it replaces the existing
259timespec64_trunc() function. This change renames our wrapper function
260to be consistent with the upstream name and updates the compatibility
261code for older kernels accordingly.

544Subject: [PATCH] Linux 5.6 compat: time_t
545
546As part of the Linux kernel's y2038 changes the time_t type has been
547fully retired. Callers are now required to use the time64_t type.
548
549Rather than move to the new type, I've removed the few remaining
550places where a time_t is used in the kernel code. They've been
551replaced with a uint64_t which is already how ZFS internally
552handled these values.
553
554Going forward we should work towards updating the remaining user
555space time_t consumers to the 64-bit interfaces.
