It is a common special case for new_inode to initialize the

Introduce a core function that does it and use it throughout
Linux.
Shouldn't this just be called new_inode_current_time()?
How is anyone going to remember what simple_new_inode() does to the
inode structure?
I noticed that most functions in libfs.c are called "simple_*" when they
do the right thing for the majority of simple use cases (e.g.,
simple_symlink_inode_operations or simple_dir_operations). I can
certainly rename the function.
Thank you for all the feedback, I will incorporate it and send a new
patch series soon.
