For RHEL 5.3, we will need to handle the cache sync command getting sent if it is fixed in BZ 430542. BZ 430542 is for the general scsi kernel fix. This BZ is for the iscsi-initiator-utils fix that will be needed to handle the new behavior.
This bugzilla has Keywords: Regression. Since no regressions are allowed between releases, it is also being proposed as a blocker for this release. Please resolve ASAP.
This is not a regression, as explained in BZ 430542. This BZ depends on BZ 430542, which was deferred to 5.4. I am moving this one to 5.4 as well.
Moving this (and BZ 430542) to 5.5.
