-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-define this type all timespec_t types have been replaced by the new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().
