Subject: [PATCH 0/4] Add binder state and statistics to binderfs

Currently, the only way to access binder state and
statistics is through debugfs. We need a way to
access the same even when debugfs is not mounted.
These patches add a mount option to make this
information available in binderfs without affecting
its presence in debugfs. The following debugfs nodes
will be made available in a binderfs instance when
mounted with the mount option 'stats=global' or 'stats=local'.

 /sys/kernel/debug/binder/failed_transaction_log
 /sys/kernel/debug/binder/proc
 /sys/kernel/debug/binder/state
 /sys/kernel/debug/binder/stats
 /sys/kernel/debug/binder/transaction_log
 /sys/kernel/debug/binder/transactions

Hridya Valsaraju (4):
  binder: add a mount option to show global stats
  binder: Add stats, state and transactions files
  binder: Make transaction_log available in binderfs
  binder: Add binder_proc logging to binderfs
