Revision 963ad94853000ab100f5ff19eea80095660d41b4 authored by Nikolay Aleksandrov on 22 July 2015, 11:03:40 UTC, committed by David S. Miller on 26 July 2015, 23:27:22 UTC
Since slave_changelink support was added there have been a few race
conditions when using br_setport() since some of the port functions it
uses require the bridge lock. It is very easy to trigger a lockup due to
some internal spin_lock() usage without bh disabled, also it's possible to
get the bridge into an inconsistent state.
