The following patch introduces in-place modification of Smack rules.
Until now Smack supported only overwriting of existing rules.
To change permitted access for a given subject and object, user had
to read list of rules to get current accesses, modify it and write
modified rule back to kernel. This way was inefficient, non-atomic
and unnecessarily difficult.
New interface is intended to ease such modifications.
Changes in v2:
- dropped patches for smackfs seq list operations
- changed modification approach to simple integer assignment
