Description

Currently, in order to build Lustre the developer needs to have access
to a full kernel source tree to build the ldiskfs kernel module. To get
around this restriction, a separate standalone ldiskfs package has been
created and is being hosted here:

https://github.com/chaos/ldiskfs

This external package provides a lustre-ldiskfs package as well as a
lustre-ldiskfs-devel package.

In order to build Lustre against this external ldiskfs package, a few
tweaks to the it's build system are needed. These have been pushed to
Gerrit in the form of the following patches:

http://review.whamcloud.com/453
http://review.whamcloud.com/1426
http://review.whamcloud.com/1427
http://review.whamcloud.com/1428

These patches are meant to maintain the current ldiskfs build
infrastructure (intree and inkernel), and only extend Lustre to build
using this external ldiskfs package.
