When creating UNIX domain sockets, the kernel used to return -ENOMEM on
error where it should return -ENFILE.  The behaviour has been wrong since
2.2.4 and fixed in the recent commit f4bd73b5a950 ("af_unix: Return errno
instead of NULL in unix_create1().").

Thanks!

The patch looks good to me, so could you ping back when this is merged 
in Linus's tree?

Cheers,

Alex

Thanks, sure!
Is that -stable?
The pull-request from net-next hit the Linus' 5.14-rc4 tree few days ago.

Ahh, if it already is in Linus's tree, I'll merge your patch.

Thanks,
