Merge tag '6.8-rc4-smb3-client-fixes' of git://git.samba.org/sfrench/cifs-2.6
Pull smb client fixes from Steve French:
"Five smb3 client fixes, most also for stable:
- Two multichannel fixes (one to fix potential handle leak on retry)
- Work around possible serious data corruption (due to change in
folios in 6.3, for cases when non standard maximum write size
negotiated)
- Symlink creation fix
- Multiuser automount fix"
