The 32bit version is needed due to logic previously added to install.pl to force the compile to be 32bit. Another way to fix this issue would be to allow 64bit version of the rnfs-utils by removing the logic which forces it to be 32bit. With the added dependency, rnfs-utils compiles on RHEL5.2 on ppc64 without issue. Thanks, Jon Hi Jon, thanks for the patch, it also works fine on RHEL5.3 now. I've also tried to install the rnfs-utils package on SLES11, and there I run into another problem. The SRPM has the following dependencies: Thanks for testing this on non-RHEL installs. [alexs...@bl3d1974 SRPMS]$ rpm -qpR rnfs-utils-1.1.5-rc1.OFED.src.rpm krb5-devel = 1.3.1 autoconf = 2.57 automake krb5-devel libtool krb5-libs rpmlib(CompressedFileNames) = 3.0.4-1 I've created the patch below for teaching the installer that rnfs-utils needs the krb5 packages. But on SLES10 11, there is no krb5-libs package, so it's not possible to install rnfs-utils. Could you try to fix this? I think the name of the package on SuSE is krb5 or krb5-server. I've attached a SRPM to this e-mail without the krb5-libs dependency. See if the package fixes any configure issues you could/will hit when trying to compile rnfs-utils. You should be able to copy the SRPM over the one in the OFED tree and it will build as it would normally. Hi Jon, after installing the tcpd-devel (for libwrap) and krb5 packages I was able to build an RPM from the SRPM you attached. This RPM has a dependency on nfs-utils, which does not exist on SLES11... Seems like they have split the package up?! Could you take care of this so that we get a clean install on SLES11? I removed the distro specific dependencies from the SRPM and added them to the install.pl for OFED. I will submit the relevant patch to install.pl shortly. You can get the SRPM of rnfs-utils without the nfs-utils dependency at: http://www.openfabrics.org/~swise/ofed_1_4/rnfs-utils/ Thanks for the testing and let me know if you hit anymore problems. On SLES11 with the rnfs-utils-1.1.5-1.OFED.src.rpm rpm I now get Installation finished successfully.

[ewg] [PATCH] NFS-RDMA: Fix page leak
In the conversion from splice_direct_to_actor to sendfile, the callback
routine was converted to the previous version without reference to the
new changes to the callback route that calls the put_page. Previously,
it had been called in svc_release_buffer, but due to significant changes
in the logic of that function it cannot be done there (and this more
closely matches what is in 2.6.28).
This fixes Bugzilla Bug 1574

[ewg] Re: [PATCH v3] mlx4_ib: Optimize hugetlab pages support
Hi Eli,
I've placed a printk in the new hugetlb function to print n and j.
While running the mckey test (attached in bugzilla), I got j=0, n=1.
Why do you say that the number of pages must cover HUGE_PAGES?
In ib_umem_get, hugetlb is set to 0 only if any of the pages is
not-hugetlb - otherwise it's 1. Am I missing something?

Yossi,
I wouldn't expect this to matter since handle_hugetlb_user_mr() only
gets called when the memory is huge pages which means the number of
PAGE_SIZE pages cover full HUGE_PAGES. You mention in Bugzilla an
mckey test but I don't know this test. Can you send how to obatain
the test and instructions how to build it and run it?
