+Subject: [PATCH] Linux 4.18 compat: inode timespec -> timespec64
+
+Commit torvalds/linux@95582b0 changes the inode i_atime, i_mtime,
+and i_ctime members form timespec's to timespec64's to make them
+2038 safe. As part of this change the current_time() function was
+also updated to return the timespec64 type.
+
+Resolve this issue by introducing a new inode_timespec_t type which
+is defined to match the timespec type used by the inode. It should
+be used when working with inode timestamps to ensure matching types.
+
+The timestruc_t type under Illumos was used in a similar fashion but
+was specified to always be a timespec_t. Rather than incorrectly
+define this type all timespec_t types have been replaced by the new
+inode_timespec_t type.
+
+Finally, the kernel and user space 'sys/time.h' headers were aligned
+with each other. They define as appropriate for the context several
+constants as macros and include static inline implementation of
+gethrestime(), gethrestime_sec(), and gethrtime().
