Subject: [SCSI] Fix issue where all hosts log nodev message for other initiators
X-Git-Tag: v2.6.13-rc4~75^2~44
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6e8215e48865bda2e07c1c0633952e35fa3b170c;p=linux-2.6

[SCSI] Fix issue where all hosts log nodev message for other initiators

Fix issue where all hosts connected to SAN get spammed with nodev
message when other initiators go away.  Display nodev message only
when FC targets go away.  However this behavior will be overridden if
LOG_DISCOVERY is set.
