bonding: Don't destroy bonding master when removing slave via sysfs
It is wrong to destroy a bonding master from a context that uses the sysfs of that bond. When last IPoIB slave is unenslaved from by writing to a sysfs file (for bond0 this would be /sys/class/net/bond0/bonding/slaves) the driver tries to destroy the bond. This is wrong and can lead to a lockup or a crash. This fix lets the bonding master stay and relies on the user to destroy the bonding master if necessary (i.e. before module ib_ipoib is unloaded) This patch affects only bonds of IPoIB slaves. Ethernet slaves stay unaffected. Signed-off-by: Moni Shoua <monis@voltaire.com> Signed-off-by: Jay Vosburgh <fubar@us.ibm.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
