Merge branch 'bridge-fix-sleep-in-atomic-context'
Ido Schimmel says:
====================
bridge: Fix sleep in atomic context
Under certain circumstances the bridge driver can call
dev_set_promiscuity() while holding the bridge spin lock. This is a
problem as dev_set_promiscuity() might sleep.
Patches #1-#2 fix the problem in the netlink and sysfs configuration
paths by only taking the lock where it is actually needed, thereby
avoiding calling dev_set_promiscuity() from an atomic context.
Patch #3 adds test cases for both configuration paths in rtnetlink.sh
which already includes test cases for similar issues.
Note that dev_set_promiscuity() can sleep either when it takes the net
device mutex or when calling netif_rx_mode_sync(). I encountered the
problem with the latter, but blamed the former since it came earlier.
