  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/

  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

  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.

  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.
