[PATCH v4 0/2] net/ibmvnic: serialization fixes

[Juliet Kim]

This series includes two fixes. The first improves reset code to allow 
linkwatch_event to proceed during reset. The second ensures that no more
than one thread runs in reset at a time. 

v2:
- Separate change param reset from do_reset()
- Return IBMVNIC_OPEN_FAILED if __ibmvnic_open fails
- Remove setting wait_for_reset to false from __ibmvnic_reset(), this
  is done in wait_for_reset()
- Move the check for force_reset_recovery from patch 1 to patch 2

v3:
- Restore reset’s successful return in open failure case

v4:
- Change resetting flag access to atomic

Juliet Kim (2):
  net/ibmvnic: unlock rtnl_lock in reset so linkwatch_event can run
  net/ibmvnic: prevent more than one thread from running in reset
