iscsi modules need to set the module reference in the host template
Last modified: 2008-05-21 11:07:25 EDT
Description of problem: If the iscsi modules do not set the module reference in the scsi host template then if iscsi is shutdown and other entities are holding a reference then they will be referencing bad memory. Version-Release number of selected component (if applicable): How reproducible: everytime Steps to Reproduce: 1. start iscsi 2. start multipath 3. stop iscsi 4. stop multipath and get oops Actual results: You get an oops Expected results: should not get a oops and the system should gracefully handle the out of order shutdown. Additional info: Patch is upstream here: http://git.kernel.org/?p=linux/kernel/git/jejb/scsi-misc-2.6.git;a=commitdiff;h=7974392c0b0d4e7a2a17ca3597d51a29b9841aa5
