3.12-stable review patch. If anyone has any objections, please let me know.
------------------ From: John Stultz <[email protected]> commit 5957324045ba2c127c9401fa3ac61ac52e043ca8 upstream. 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!)
