X-Git-Tag: v2.6.38-rc6~32^2 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1621dbbdb90f42b7bd14aea1c44ee49b558d1b1a;p=pandora-kernel.git [SCSI] qla2xxx: Return DID_NO_CONNECT when FC device is lost. If the target device gets lost, this fix is needed, as it causes negative unintended responses on basic I/O tests. If the target device gets lost, the upstream qla2xxx driver returns SCSI_MLQUEUE_TARGET_BUSY which causes an immediate retry without drop in the number of allowed retries. This semantic change, as a result of removing FC_DEVICE_LOST check is reasonable, as it only extends a short transitional period, until the transport is called to notify that the rport as lost (fc_remote_port_delete()). Once transport notification is done, fc_remote_port_chkready() check will take over.
