We are running running short of vma->vm_flags. We can avoid needing a
new VM_* flag in some cases if the original @flags submitted to mmap(2)
is made available to the ->mmap() 'struct file_operations'
implementation. For example, the proposed addition of MAP_DIRECT can be
implemented without taking up a new vm_flags bit. Another motivation to
avoid vm_flags is that they appear in /proc/$pid/smaps, and we have seen
software that tries to dangerously (TOCTOU) read smaps to infer the
behavior of a virtual address range.
This conversion was performed by the following semantic patch. There
were a few manual edits for oddities like proc_reg_mmap.
Thanks to Julia for helping me with coccinelle iteration to cover cases
where the mmap routine is defined in a separate file from the 'struct
file_operations' instance that consumes it.
// Usage:
// $ spatch mmap.cocci --no-includes --include-headers --dir .
