 14           This option enables Lustre file system client support. Choose Y
 15           here if you want to access a Lustre file system cluster. To compile
 16           this file system support as a module, choose M here: the module will
 17           be called lustre.
 18 
 19           To mount Lustre file systems, you also need to install the user space
 20           mount.lustre and other user space commands which can be found in the
 21           lustre-client package, available from
 22           http://downloads.whamcloud.com/public/lustre/
 23 
 24           Lustre file system is the most popular cluster file system in high
 25           performance computing. Source code of both kernel space and user space
 26           Lustre components can also be found at
 27           http://git.whamcloud.com/?p=fs/lustre-release.git;a=summary

 29           If unsure, say N.

 37         help
 38           This option defines the maximum size of buffer in bytes that user space
 39           applications can pass to Lustre kernel module through ioctl interface.
 40 
 41           If unsure, use default.

 45         depends on LUSTRE_FS
 46         help
 47           This option is mainly for debug purpose. It enables Lustre code to do
 48           expensive checks that may have a performance impact.
 49 
 50           Use with caution. If unsure, say N.
