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:
