Hi Linus,

Here are some fixes for the afs filesystem:

 (1) Fix the decoding of fetched file status records so that the xdr
     pointer is advanced under all circumstances.

 (2) Fix the decoding of a fetched file status record that indicates an
     inline abort (ie. an error) so that it sets the flag saying the
     decoder stored the abort code.

 (3) Fix the decoding of the result of the rename operation so that it
     doesn't skip the decoding of the second fetched file status (ie. that
     of the dest dir) in the case that the source and dest dirs were the
     same as this causes the xdr pointer not to be advanced, leading to
     incorrect decoding of subsequent parts of the reply.

 (4) Fix the dump of a bad YFSFetchStatus record to dump the full length.

 (5) Fix a race between local editing of directory contents and accessing
     the dir for reading or d_revalidate by using the same lock in both.

 (6) Fix afs_d_revalidate() to not accidentally reverse the version on a
     dentry when it's meant to be bringing it forward.

David
