Re: [PATCH v2 1/3] mm, oom: move task_will_free_mem up in the file to be used in process_mrelease

process_mrelease needs to be added in the CONFIG_MMU-dependent block which
comes before __task_will_free_mem and task_will_free_mem. Move these
functions before this block so that new process_mrelease syscall can use
them.

changes in v2:
- Fixed build error when CONFIG_MMU=n, reported by kernel test robot. This
required moving task_will_free_mem implemented in the first patch
- Renamed process_reap to process_mrelease, per majority of votes
- Replaced "dying process" with "process which was sent a SIGKILL signal" in
the manual page text, per Florian Weimer
- Added ERRORS section in the manual page text
- Resolved conflicts in syscall numbers caused by the new memfd_secret syscall
- Separated boilerplate code wiring-up the new syscall into a separate patch
to facilitate the review process

TBH, I really dislike this move as it makes git blame a lot harder with 
any real benefit.

Can't you just use prototypes to avoid the move for now in patch #2?

static bool task_will_free_mem(struct task_struct *task);
