Could you please look into this as your top priority?

Thanks

yes, sure

The kernel that the patch landed was RHEL6.3 2.6.32-279.22.1.el6
ofed-1.5.4 does not support this kernel

o Linux Operating Systems:

• RedHat EL5 up6 2.6.18-238.el5
• RedHat EL5 up7 2.6.18-274.el5
• RedHat EL6 2.6.32-71.el6
• RedHat EL6.1 2.6.32-131.0.15.el6
• RedHat EL6.2 2.6.32-220.el6

[Minh Diep]

We should move the build system to http://www.openfabrics.org/downloads/OFED/release_notes/OFED_3.5_release_notes

[Peter Jones]

So essentially this issue is a duplicate of LU-1468?

[Minh Diep]

I don't think so. It's interesting that lustre-master is building 2.6.32.279.19.1.el6 on ofed 1.5.4 and passes. I'll investigate this more by building this manually.

[Minh Diep]

Ofed define this in rcupdate.h

#include_next <linux/rcupdate.h>

#define RCU_INIT_POINTER(p, v) p = v

starting kernel 2.6.32-279.22.1 rcupdate also define

/**

• RCU_INIT_POINTER() - initialize an RCU protected pointer
  *
• Initialize an RCU-protected pointer in such a way to avoid RCU-lockdep
• splats.
  */
  #define RCU_INIT_POINTER(p, v) \
  p = (typeof(*v) __force __rcu *)(v)

This caused conflict redefine during the build

[Minh Diep]

I have confirmed that it need ofed 3.5. This means this issue is a duplicate of LU-1468
