Our you could think outside the circle:
Store all your small files as symlinks, then use symlink to create
them and readlink to read them. (You would probably end up use
symlinkat and readlinkat).
Only one system call instead of three.
I guess you don't get meaningful

Now, to be fair, there are probably a number of cases where
open/lseek/readv/close and open/lseek/writev/close would be worth doing

Code needs a kfree of the name returned by create_unique_id, and I
think ID_STR_LENGTH needs to be at least 34.
Maybe that should

As I said in some earlier discussion following my original patch, that
would be fine with me. I haven't coded up that variant, but it's simple
enough. Would you like to do it?
Sure.
