Patchless Client

Patchless Client
As of Lustre 1.6.0, Lustre supports running the client modules on some unpatched "stock" kernels. This results in some small performance losses, but may be worthwhile to some users for maintenance or contract reasons.

We will typically post a "patchless" RPM at the download site. Instead, if building from source, the Lustre configure script will automatically detect the unpatched kernel and disable building the servers.

Currently, the patchless client works with these kernel versions
