Lorenzo Stoakes b013ed4031 fs: consistently use can_mmap_file() helper ... Since commit c84bf6dd2b ("mm: introduce new .mmap_prepare() file callback"), the f_op->mmap() hook has been deprecated in favour of f_op->mmap_prepare(). Additionally, commit bb666b7c27 ("mm: add mmap_prepare() compatibility layer for nested file systems") permits the use of the .mmap_prepare() hook even in nested filesystems like overlayfs. There are a number of places where we check only for f_op->mmap - this is incorrect now mmap_prepare exists, so update all of these to use the general helper can_mmap_file(). Most notably, this updates the elf logic to allow for the ability to execute binaries on filesystems which have the .mmap_prepare hook, but additionally we update nested filesystems.
