[Xen-devel] [PATCH] Avoid race condition when creating or destroying network bridges

[Masaki Kanno <kanno.masaki@xxxxxxxxxxxxxx>]

Hi,

I saw the following message when I created or destroyed two bridges 
by using network-bridge script at same time.  Of course names of the 
bridges are different.  But, a temporal name "tmpbridge" is used by 
the script to create or destroy the bridges.  I think that the message 
was shown by "tmpbridge".

  SIOCSIFNAME: File exists

This patch avoids race condition when creating or destroying the 
bridges.

Best regards,
 Kan
