This patch makes a variety of cleanup changes to all libfc files. This patch adds kernel-doc headers to all functions lacking them and attempts to better format existing headers. It also add kernel-doc headers to structures. This patch ensures that the current naming conventions for local ports, remote ports and remote port private data is upheld in the following manner. struct instance (i.e. variable name) -------------------------------------------------- fc_lport lport fc_rport rport fc_rport_libfc_priv rpriv fc_rport_priv rdata I also renamed dns_rp and ptp_rp to dns_rdata and ptp_rdata respectively. I used emacs 'indent-region' and 'tabify' on all libfc files to correct spacing alignments. I feel sorry for anyone attempting to review this patch.
