Hi,
I got a trouble while I am developing a patch for EXT4 filesytem.
Actually, I used a percpu rw semaphore in my patch and there was no
problem when I built EXT4 filesystem as built-in mode. However, when
kbuild auto build robot built EXT4 filesystem with my patch as a "module",
a bulid error occurred because percpu_free_rwsem() function is not exported.
I noticed that other functions except percpu_free_rwsem() were exported in 2015.
Is there any reason for percpu_free_rwsem() not to be exported?
If I need the function to be exported, should I do that in my patch? :-)
Best Regards,

Sounds like a question for the ext4 maintainers. You can find them in
the MAINTAINERS file.
Thanx, Paul
