RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Peter Pols 2011-05-20 13:44:48 UTC 
Compiling error for FusionIO driver iomemory-vsl 2.2.3.66 with RHEL6.1 GA:
/builddir/build/BUILD/iomemory-vsl-2.2.3.66/root/usr/src/iomemory-vsl/obj/default/kblock.c: In function 'kfio_handle_special_req':
/builddir/build/BUILD/iomemory-vsl-2.2.3.66/root/usr/src/iomemory-vsl/obj/default/kblock.c:402: error: implicit declaration of function 'blk_barrier_rq'
 
Additional info:
With RHEL6.0 'blk_barrier_rq' was defined in include/linux/blkdev.h
Comment 3 Mike Snitzer 2011-05-20 15:31:40 UTC 
blk_barrier_rq is not part of kABI and was dropped when the FLUSH/FUA advances were ported to RHEL 6.1.

We've already coordinated with Fusion-io and they have provided a fixed src.rpm for their iomemory-vsl driver, see:
