[RFCv0 0/5] Bluetooth: Change socket lock to l2cap_chan lock

From: Andrei Emeltchenko <redacted>

This is DRAFT RFC introducing l2cap channel lock. Please make suggestion how to
make it better.

Beside changing socket locks to l2cap_chan lock channel list lock is reverted.
It is now used to protect RCU updaters or RCU lists which might sleep and not
protected by rcu_read_lock.

Andrei Emeltchenko (5):
  Bluetooth: Use locks in RCU updater code
  Bluetooth: Add l2cap_chan_lock
  Bluetooth: Helper functions for locking change
  Bluetooth: Remove unneeded sk variable
  Bluetooth: Change sk lock to l2cap_chan lock
