Putting in NEEDINFO pending upstream code acceptance. Code is upstream since v2.6.28 Commit 242f9dcb8ba6f68fcd217a119a7648a4f69290e9 There was commit fixes post the initial commit. OK, marking as MODIFIED. The feature requested has already been accepted into the upstream code base planned for the next major release of Red Hat Enterprise Linux. When the next milestone release of Red Hat Enterprise Linux 6 is available, please verify that the feature requested is present and functioning as desired. Closing as support is available in current release. ------- Comment From andmike.ibm.com 2010-05-13 15:27 EDT------- 1.) During testing on a power system a race between blk_abort_queue and the scsi_request_fn was discovered. Using a debug patch which injects blk_abort_queue calls every 5 seconds I am able to see a race on my lab system. I am working on a patch and I will post to linux-scsi shortly Here is the post on the issue. http://article.gmane.org/gmane.linux.scsi/58865 I am currently working this issue on linux-scsi. 2.) I also posted a bug fix to address a scsi command leak in the patch series listed below. I will try backport just this change and attach to this bug. http://thread.gmane.org/gmane.linux.scsi/58669 ------- Comment From malahal.com 2010-06-06 17:52 EDT------- tested with 'dmsetup message' and 'multipathd -k, followed by "fail path <path>"' commands to simulate failures. I see the SCSI layer immediately aborting commands from the messages in syslog. |
