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: // $
