-Subject: [PATCH] supermin: Fix IBM Virtual SCSI driver name
-
-The driver was renamed from ibmvscsic to ibmvscsi on kernel 3.7.
-See https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=9965c2f19be470c452357ae4f6304467cdeada55
-
-The old name is kept so supermin works with recent kernels as well as kernel
-version older than 3.7.
