Subject: mm/vma: rename __mmap_prepare() function to avoid confusion
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=fe513de60b2705f6c6bb14a11f2a16b9c14c676e;p=users%2Fjedix%2Flinux-maple.git

mm/vma: rename __mmap_prepare() function to avoid confusion

Now we have the f_op->mmap_prepare() hook, having a static function called
__mmap_prepare() that has nothing to do with it is confusing, so rename
the function to __mmap_setup().
