[LU-7962] Support build against weak-module ZFS install

• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.9.0
• Labels: patch
• Severity: 3
• Assignee: Nathaniel Clark
• Reporter: Christopher Morrone (Inactive)

Description

ZFS support weak module updates, ZFS does will not always be built for every specific kernel that is installed. Unfortunately, some directories that Lustre needs from ZFS and SPL have a kernel string embedded in them, and now that kernel string will potentially be different than the kernel that Lustre is building against.

As a work around we can update the Lustre build scripts to just select the last subdirectory that has a kernel name from the ZFS and SPL build directories as a directory that Lustre should use in its build. Its as reasonable a guess as I can figure we can easily make.
