http://review.whamcloud.com/#/c/8116 looks ready for inspection and possible merger.
I think LU-4209 already exists to address the problem with O_LOV_DELAY_CREATE.
O_LOV_DELAY_CREATE conflict with __O_TMPFILE. Need change it. lod and osp procfs patch need fix some bug. I have commented in gerrit.
Ran several jobs (various IOR, mdtest configurations and a science app) against the 3.11 base lustre file system using ldiskfs. It was successful so I would say we are in pretty good shape.
One odd quirk. lustre-ldiskfs.spec is setup with a Requires: modutils. However there isn't any rpm in fedora that provides modutils. I could only install lustre with a --force option on the command line.
Looks like in earlier distro modutils was one of the Provides: in the module-init-tools rpm. The fedora rpm that contains similar files as the old module-init-tools rpm is named kmod, but it has no Provides: modutils in it.
it lives, take II
I'm seeing first signs of life now with ldiskfs in fc19:

Send it my way. I will try it out. Tomorrow I will setup a real file system using a 3.11 kernel to see how it holds up. If it holds up I plan to mount it on our cray test bed and run a bunch of jobs to stress test it.
I was using Peng's original upstream patch. I see #8237 now.
By the way I do have a prototype autoconf patch that selects the ldiskfs series. I haven't pushed it because I'm not sure it's production worthy.
Yes with the refresh now all I have to do is set the ldiskfs series manually. Also you need patch http://review.whamcloud.com/#/c/8237 which I just pushed. I also updated http://review.whamcloud.com/#/c/8116 locally to test if ext4_map_blocks() is available.
with the refresh of #7794 and the addition of #8231 I can now complete a full server build with ldiskfs on the 3.11.7 kernel that is current in fc19 too.
major milestone!!
I'm almost afraid to try some functional tests.
James, can you describe the changes you needed in ldiskfs patches? They worked for me as is.
I see patch 8116 has been abandon. I believe the point of the patch was to limit the port of patches for fc19 support. Do this mean the ldiskfs patches will be updated or will the rhel6.5 patch be enough?
