  14        help
  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

  37        default 8192
  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.

  44config LUSTRE_DEBUG_EXPENSIVE_CHECK
  45        bool "Enable Lustre DEBUG checks"
  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.
