[PATCH 1/1] scsi: storvsc: Support manual scan of FC hosts on Hyper-V

From: K. Y. Srinivasan
Date: Sat Mar 12 2016 - 15:16:48 EST


The default user scan function associated with FC (fc_user_scan)
is not suitable for FC hosts on Hyper-V since we don't have
an rport associated with FC host on Hyper-V . Set it to NULL so we can
support manual scan of FC targets on Hyper-V.
