Security update for Linux kernel
The SUSE Linux Enterprise 11 Service Pack 2 kernel was updated to fix a regression introduced by the previous update:
* scsi_dh_alua: Incorrect reference counting in the SCSI ALUA
initialization code lead to system crashes on boot (bnc#858831).
As the update introducing the regression was marked security, this is also marked security even though this bug is not security relevant.
