Subject: [SCSI] ibmvfc: Fix adapter cancel flags for terminate_rport_io
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4a5c4a5ed2b8b7fac68368e7ab8cb415dd006418;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[SCSI] ibmvfc: Fix adapter cancel flags for terminate_rport_io

When issuing a Cancel to the virtual fibre channel adapter,
the interface specifies a flags field for the client to indicate
what kind of error recovery is being performed. Fix up these
flags for terminate_rport_io to indicate an abort task set
rather than a target reset.
