Michel Lespinasse 6febc3942c BACKPORT: FROMLIST: f2fs: implement speculative fault handling 
We just need to make sure f2fs_filemap_fault() doesn't block in the
speculative case as it is called with an rcu read lock held.

Signed-off-by: Michel Lespinasse <michel@lespinasse.org>
Link: https://lore.kernel.org/all/20210407014502.24091-33-michel@lespinasse.org/

Conflicts:
    fs/f2fs/file.c

1. The change in f2fs_filemap_fault is not needed since i_mmap_sem is not
used anymore.
