            I updated the PFL user guide per Niu's comment. The changes include:

            • added commands/example to set default PFL layout to an existing directory
            • added all kinds of PFL related "lfs getstripe" commands
            • added all kinds of PFL related "lfs find" commands

            Please have a check. Thanks!

            I think it's worth to mention that 'lfs find support layout component options now, and give some example of set default PFL layout to a directory or mount point.

            The way to provide optional argument for 'lfs getstripe' is changed by https://review.whamcloud.com/#/c/26491/ , you need to update your document, thanks.

            It's a great user guide about PFL usage with graph and example illustration. I made a little adjustment recommendation in the uploaded doc.
