-# --without-ldiskfs - Disable ldiskfs support.

-#
-# --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.
