[PATCH v7 08/13] fs: drop the timespec64 argument from update_time

Jeff Layton
2023-08-07T19:41:41Z

Now that all of the update_time operations are prepared for it, we can
drop the timespec64 argument from the update_time operation. Do that and
remove it from some associated functions like inode_update_time and
inode_needs_update_time.
