Hopefully this isn't too late for 3.12. In commit 7dc19d5aff (convert shrinkers to new count/scan API) the return value to PURGE_ALL_CACHES was dropped, causing -EPERM to always be returned.
This patch re-adds the ret assignment, setting it to the the ashmem_shrink_count(), which is the lru_count. (Sorry this was missed in the review!)
