[lustre-discuss] Lustre Client on Fedora 23

[Dilger, Andreas]

The current Lustre hasn't been updated to the 4.7 kernel yet.  As you
see the newer kernel replaced PAGE_CACHE_* with PAGE_*.  A patch to
fix that (basically simple search and replace) would be welcome.  You
should also add PAGE_CACHE_SHIFT and PAGE_CACHE_SIZE into
contrib/scripts/checkpatch.pl::dep_functions so that any future patches
trying to add them will be flagged.

See http://wiki.lustre.org/Submitting_Changes for details.  I've filed
LU-8661 to track patches needed for Linux 4.7 kernels so you can use
that for your patch submission.

Cheers, Andreas

    Looks like I may be stuck.  I went to the build directory and ran 
    ./configure manually which seemed to work but make fails to build.

    Here is the make output which appears to be an issue with the 
    libcfs_string.h file.
