[CRIU] ARMv5 implementation counter value

[Maikel Coenen]

Hi,

I am almost done with implementing ARMv5 implementation of CRIU but currently stuck at researching the input arguments of the function atomic_add_return and atomic_sub_return.
These functions make use of the atomic_t struct with a counter in it but I want to know what possible values this counter can be, so I can make some kind of mutex for it.

Can someone help me with this question?
