Y. Srinivasan" <kys@...rosoft.com> Subject: [PATCH 1/1] scsi: storvsc: Support manual scan of FC hosts on Hyper-V 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. Signed-off-by: K. Y.
