Hi Yang Sheng,

What is the status of this ticket? I am going to work on latest kernel support for upstream kernel (which is 3.8 now) and would like to coordinate with you so that we duplicate efforts.

Thanks,
Tao

Can this ticket be linked to LU-2850 since the work over laps. The patches here are more up to date but LU-2850 has additional patches that missing here.

[James A Simmons]

This can also be linked to LU-1812. Also some patches from LU-2800 are needed.

[James A Simmons]

Since my patch from LU-1812 impacts this work I piece together a recipe to be able to build a fc18 lustre ZFS server. The patches needed are:

http://review.whamcloud.com/#change,4649 - LU-1812 kernel: 3.0/SuSE and 3.6/FC18 server patches
http://review.whamcloud.com/#change,5973 - LU-2686 kernel: sock_map_fd replaced by sock_alloc_file
http://review.whamcloud.com/#change,5974 - LU-2686 kernel: Kernel update for 3.7.2-201.fc18
http://review.whamcloud.com/#change,5768 - LU-2850 compat: posix_acl_

http://review.whamcloud.com/#change,5763 - LU-2987 llite: rcu-free inode

With this the build only fails with an:

lustre-2.3.63/libcfs/libcfs/linux/linux-lwt.c:60: error: ‘struct task_struct’ has no member named ‘oomkilladj’

I could not find a patch for this.

After http://review.whamcloud.com/5655 be landed. This problem will disappear.

[James A Simmons]

It is safe to say we can label this as a 2.5 item now.

[Alexey Shvetsov]

Seems all patches was merged to master

[James A Simmons]

Peter can you close this ticket.

[Yang Sheng]
