Ah! Nice catch. I am not sure how I missed that while making 178ba1e0d00aca671f9a8f5f41d28fc0fe717752, it's also strange that this never triggered any ill effects in any of my testing. Thanks! On Feb 25, 2015, at 8:20 AM, Dan Carpenter wrote: From the indenting, it looks like curly braces

Hello! No, it's not the way to test the kernel version, it's the way to test internal lustre version. Either way maintaining compatibility with Lustre 1.8 and 2.0 servers should not be important anymore, so it's fine to drop this check indeed. Bye, Oleg On Oct 11, 2014, at 5:06

Thanks! Actually, I do't think this function is useful on the client. From the name of it, it would have been used in the server code, but even there it was recently removed as I now see. I'll submit a removal patch. On Sep 8, 2014, at 6:38 PM, Dan Carpenter wrote: On Tue, Sep 09, 2014 at
