-#
-# --with-ldiskfs      - Enable ldiskfs support and attempt to autodetect the
-# --with-ldiskfs=yes    headers in one of the following places in this order:
-#                       * ./ldiskfs
-#                       * /usr/src/ldiskfs-*/$LINUXRELEASE
-#                       * ../ldiskfs
-#
-# --with-ldiskfs=path - Enable ldiskfs support and use the headers in the
-#                       provided path.  No autodetection is performed.
-#
-# --with-ldiskfs-obj  - When ldiskfs support is enabled the object directory
-#                       will be based on the --with-ldiskfs directory.  If
-#                       this is detected incorrectly it can be explicitly
-#                       specified using this option.
-#
-# NOTE: As with all external packages ldiskfs is expected to already be
-# configured and built.  However, if the ldiskfs tree is located in-tree
-# (./ldiskfs) then it will be configured and built recursively as part of
-# the lustre build system.
-#
-# NOTE: The lustre and in-tree ldiskfs build systems both make use these
-# macros.  This is undesirable and confusing at best, it is potentially
-# danagerous at worst.  The ldiskfs build system should be entirely stand
-# alone without dependency on the lustre build system.
