Hi, this is your Linux kernel regression tracker.

I noticed a regression report in bugzilla.kernel.org. As many (most?)
kernel developer don't keep an eye on it, I decided to forward it by
mail. Quoting from https://bugzilla.kernel.org/show_bug.cgi?id=216881 :

>  Kim Scarborough 2023-01-04 07:00:50 UTC
> 
> An SMB mount to a Windows XP machine in my fstab no longer works. It last worked with 6.0.9. fstab line:
> 
> //server/D /remote/server/D cifs noauto,_netdev,username=example,password=example,uid=1000,vers=1.0,nomultichannel 0 0
> 
> When I attempt to mount this now, I get the following error:
> 
> mount error(20): Not a directory
> 
> dmesg shows:
> 
> CIFS: VFS: bogus file nlink value 0

See the ticket for more details.

BTW, let me use this mail to also add the report to the list of tracked
regressions to ensure it's doesn't fall through the cracks:

#regzbot introduced: v6.0..v6.1
https://bugzilla.kernel.org/show_bug.cgi?id=216881
#regzbot title: cifs: cifs 1.0 mounts fail with "VFS: bogus file nlink
value 0"
#regzbot ignore-activity

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)
