Summary0008053: xfs still failed to allocate memory using linux 3.10 that patched commit b3f0
DescriptionHi,
We test our ceph cluster I/O performance, and then one osd node down.
Finally, I found the reason is xfs failed to allocate memory:
http://tracker.ceph.com/issues/6301

And in that report the resolver of this XFS problem is update kernel to 3.14rc1:
One fix has been integrated in kernel commit b3f03bac8132207a20286d5602eda64500c19724
(3.14rc1).

Here is the difference of commit b3f0:
https://git.kernel.org/cgit/linux/kernel/git/dgc/linux-xfs.git/commit/?id=b3f03bac8132207a20286d5602eda64500c19724

and my kernel version:
# uname -r
3.10.0-123.el7.x86_64
For some reason, I would not want to upgrade kernel 3.10.0 to 3.14rc1,
So I tried to recompile xfs module with the commit b3f0,
But, after I download the kernel source code:
http://vault.centos.org/7.0.1406/os/Source/SPackages/kernel-3.10.0-123.el7.src.rpm
I found 3.10.0 already patched the commit, so is that means my xfs included the patch and still does not work?
If that is right, I also can't understand why centos kernel-3.10.0 include 3.14rc1 bug fixed commit.

I'm new boy here, describe not very clear, waiting for your helps, thanks.
