Ou, it really is not released yet. I was just rebasing my branch on top
of the Linus's master branch and somehow I thought that changes which
"git rebase" dropped from my branch were already released.

So sure, first the change needs to be released and then it could be
proposed for backporting.

I would propose to backport these two commits (in this order):
ca4b2c460743 ("fs/smb/client: avoid querying SMB2_OP_QUERY_WSL_EA for SMB3 POSIX")
3681c74d342d ("smb: client: handle lack of EA support in smb2_query_path_info()")

into all stable branches which already contain this commit:
ea41367b2a60 ("smb: client: introduce SMB2_OP_QUERY_WSL_EA")

Hopefully it is clear now.
