Merge tag '5.19-rc1-smb3-client-fixes' of git://git.samba.org/sfrench/cifs-2.6
Pull cifs client fixes from Steve French: "Three reconnect fixes, all for stable as well. One of these three reconnect fixes does address a problem with multichannel reconnect, but this does not include the additional fix (still being tested) for dynamically detecting multichannel adapter changes which will improve those reconnect scenarios even more" * tag '5.19-rc1-smb3-client-fixes' of git://git.samba.org/sfrench/cifs-2.6: cifs: populate empty hostnames for extra channels cifs: return errors during session setup during reconnects cifs: fix reconnect on smb3 mount types
