All the callers of vm_mmap seem to check for the failure already
and bail out in one way or another on the error which means that

Hmm I'm not that sure about this one:
17 1071 fs/binfmt_elf.c <<load_elf_binary>>

Assigns result of vm_mmap() to "error" variable which is never checked. Shouldn't __must_check trigger here?
