If not affected, prog stay blocked

Hi,

I have patched my system before to try your program, and it stay stuck on :

testc0w@host:/tmp/dirty_cow_test$ ./dirtyc0w foo m00000000000000000
mmap 7f141ebae000

Nothing happen until I Ctrl + C

This is files mode :

testc0w@host:/tmp/dirty_cow_test$ ls -lh
total 20K
-rwxr-xr-x 1 testc0w testc0w 9,7K nov.  13 19:07 dirtyc0w
-rw-r--r-- 1 testc0w testc0w 2,8K nov.  13 19:07 dirtyc0w.c
-r-----r-- 1 root    root      32 nov.  13 19:07 foo

Is it the behaviour expected when there is no problem on the kernel ?

Thanks for your help !

I'm sorry finally, it works but it tooks almost 20 minutes...

testc0w@srv-nas:/tmp/dirty_cow_test$ time ./dirtyc0w foo m00000000000000000
mmap 7f64f6b25000
madvise 0
procselfmem 1800000000

real    17m48.132s
user    1m2.980s
sys 25m23.108s

Is it normal ?

Thx !
