From: Christof Schmitt Date: Thu, 8 Jul 2010 07:53:08 +0000 (+0200) Subject: [SCSI] zfcp: Use forced_reopen in terminate_rport_io callback X-Git-Tag: v2.6.36-rc1~570^2~12 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=835dc29887073eec7817559a07558f955383d099;p=profile%2Fivi%2Fkernel-adaptation-intel-automotive.git [SCSI] zfcp: Use forced_reopen in terminate_rport_io callback When running in non-NPIV mode, the port_reopen in terminate_rport_io might succeed even though the remote port is not available. If the same port connection is held open from another operating system, the reopen is only a virtual operation and might not hit the SAN. Fix this by changing the call to forced_reopen that forces a logout/login operation in the SAN.
