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

 30           If unsure, say N.

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

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