Patch series "userfaultfd: merge fs/userfaultfd.c into mm/userfaultfd.c", v3. These patches merge fs/userfaultfd.c into mm/userfaultfd.c and make functions used only inside mm/userfaultfd.c static. This patch (of 2): Historically userfaultfd implementation has been split between fs/userfaultfd.c and mm/userfaultfd.c. The mm/ part implemented memory management operations, while the fs/ part implemented file descriptor handling and called into the mm/ part for the actual memory management work. This separation is quite artificial and fs/userfaultfd.c does not seem to belong to fs/ because it's only a user if vfs APIs and like for other users, for example, memfd and secretmem, the file descriptor handling could live in mm/ as well. "Append" fs/userfaultfd.c to mm/userfaultfd and update fs/Makefile and MAINTAINERS accordingly. No intended functional changes.
