| |
Hello, I am attempting to work on replacing the kmap[_atomic]() calls by kmap_local_page() function call. A detail on this change can be found here [0].
I would like to know if this function: arch/loongarch/mm/init.c::copy_user_highpage() is currently in use or is it a dead code?
If this code is not in use, can this be removed instead? However, if it is in use, can you comment why kmap_atomic() was preferred over kmap() function call?

Thank you, Deepak.
