Now, event counter per memcg is updated only when\n memory usage is over soft limit. Here, considering hierarchical memcg\n management, ancesotors should be taken care of.\n\n Now, ancerstors(hierarchy) are handled in charge() but not in uncharge().\n This is not good.\n\n Prolems:\n 1. memcg\u0027s event counter incremented only when softlimit hits. That\u0027s bad.\n It makes event counter hard to be reused for other purpose.\n\n 2. At uncharge, only the lowest level rescounter is handled.

No \"if\" sentense is better.\n\nFixes:\n * Removed soft_limit_xx poitner and checks in charge and uncharge.\n Do-check-only-when-necessary scheme works enough well without them.\n\n * make event-counter of memcg incremented at every charge/uncharge.\n (per-cpu area will be accessed soon anyway)\n\n * All ancestors are checked at soft-limit-check.
