    afs: Locally edit directory data for mkdir/create/unlink/... · 63a4681f
    David Howells authored
    Locally edit the contents of an AFS directory upon a successful inode
    operation that modifies that directory (such as mkdir, create and unlink)
    so that we can avoid the current practice of re-downloading the directory
    after each change.
    This is viable provided that the directory version number we get back from
    the modifying RPC op is exactly incremented by 1 from what we had
    previously.  The data in the directory contents is in a defined format that
    we have to parse locally to perform lookups and readdir, so modifying isn't
    a problem.
    If the edit fails, we just clear the VALID flag on the directory and it
    will be reloaded next time it is needed.
