Commit 9a6cdf52b85e "xen-netback: fix memory leaks on XenBus disconnect" added missing code to fix a memory leak by calling vfree() in the appropriate place. Unfortunately subsequent commit f16f1df65f1c "xen-netback: protect resource cleaning on XenBus disconnect" then wrapped this call to vfree() in a spin lock, leading to a BUG due to incorrect context.
Patch #1 makes the existing code more readable Patch #2 fixes the problem Paul Durrant (2): xen-netback: keep a local pointer for vif in backend_disconnect() xen-netback: don't vfree() queues under spinlock drivers/net/xen-netback/xenbus.c | 31 +++++++++++++++++++------------ 1 file changed, 19 insertions(+), 12 deletions(-) -- 2.1.4
