Subject: [PATCH] b=2811 HP's utils_pagesize_issues.patch:

Info:
        HP SFS 1678
        Enhance the lfs command to warn if stripe size is not an exact
        multiple of page size.

        HP SFS 211/CFS 2811
        Fix the lctl command to use dynamically calculated page size
        rather than compiled in page size setting. This means the command
        doesn't need to be rebuilt/re-installed if we reboot on a kernel
        with a different page size.
