So, you need that a738c93fb1c1 ("cifs: Set CIFS_MOUNT_USE_PREFIX_PATH
flag on setting cifs_sb->prepath.") merged to where exactly?

> 2. Due to a major change that went into the 5.11 kernel (the new mount API support), the code differs significantly, and the missing patch cannot be applied to pre-5.11 trees.
> Hence, Paulo submitted the attached patch (cifs: fix prefix path in dfs mounts), which fixes this for pre-5.11 kernels.

Can you submit this in a proper format (i.e. not dos line ends, and good
changelog and most importantly, YOUR signed off by on it saying that the
patch came through you?

Make this a 2 patch series please, and be specific as to what tree(s)
this needs to be backported to, and I will be glad to review it.

thnaks,
