Merge tag '5.19-rc2-smb3-client-fixes' of git://git.samba.org/sfrench/cifs-2.6
Pull cifs client fixes from Steve French:
"Two cifs debugging improvements - one found to deal with debugging a
multichannel problem and one for a recent fallocate issue
This does include the two larger multichannel reconnect (dynamically
adjusting interfaces on reconnect) patches, because we recently found
an additional problem with multichannel to one server type that I want
to include at the same time"
* tag '5.19-rc2-smb3-client-fixes' of git://git.samba.org/sfrench/cifs-2.6:
cifs: when a channel is not found for server, log its connection id
smb3: add trace point for SMB2_set_eof
