Hi all,
This is my first pass at parent pointer attributes for xfs. It's also
my first patch set for xfs in general, so I would very much appreciate
the feedback. I got in touch with Brian Foster a while back, who was
gracious enough to give me what he had done thus far with it. From
there I've finished out the remove and rename routines. This
implementation uses the following on disk format:
name={parent inode, parent inode gen, dirent offset}
value={dirent filename}
I know folks have a lot of opinions about the format, so I'd
like to get peoples thoughts on it now that we have some code
to look at and discuss. Thanks!
Questions, comments and feedback are welcome!
