Konstantin Khlebnikov bafb282df2 c/r: prctl: update prctl_set_mm_exe_file() after mm->num_exe_file_vmas removal ... A fix for commit b32dfe3771 ("c/r: prctl: add ability to set new mm_struct::exe_file"). After removing mm->num_exe_file_vmas kernel keeps mm->exe_file until final mmput(), it never becomes NULL while task is alive. We can check for other mapped files in mm instead of checking mm->num_exe_file_vmas, and mark mm with flag MMF_EXE_FILE_CHANGED in order to forbid second changing of mm->exe_file.
