[patch 3/10] s390: set online race in the lcs driver. From: Michael Holzheu <holzheu@de.ibm.com> There is a race between lcs_stopcard() and lcs_open_device() which can lead to the error 'lcs: Error in starting channel, rc=-16'. lcs_open_device() is invoked when 'ifconfig up' is called due to a hotplug event, which is caused by register_netdev(). In parallel lcs_stopcard() is executed. Both functions are sending lcs commands. The second invocation fails with -EBUSY (-16) as return value. Move invocation of register_netdev() after invocation of lcs_stopcard to avoid the race. Signed-off-by: Frank Pavlic <pavlic@de.ibm.com> |
