When patching a kernel by following https://wiki.hpdd.intel.com/pages/viewpage.action?pageId=8126821, the instructions say:

--  link the Lustre series and patches

# ln -s ~/lustre-release/lustre/kernel_patches/series/2.6-rhel6.series series

# ln -s ~/lustre-release/lustre/kernel_patches/patches patches

--  Apply the patches to the kernel source using quilt

# quilt push -av

...

In Lustre 2.1.6, the file lustre/kernel_patches/series/2.6-rhel6.series (which is where the link is made to) has only 8 patch files, while the file ldiskfs/kernel_patches/series/ldiskfs-2.6-rhel6.series has 34 patches.

Why do we use one, and not the other.  Or, do we need both?
