By that you mean that you can use absolute or relative paths instead of
file descriptors?

I'm not following this argument currently. In what sense does opening
special files return a VFS special inode and how does that prevent
FS_IOC_FSSEETXATTR from working? The inode in
static int ioctl_fssetxattr(struct file *file, void __user *argp)
{
struct mnt_idmap *idmap = file_mnt_idmap(file);
struct dentry *dentry = file->f_path.dentry;
d_inode(dentry)
and your:
error = user_path_at(dfd, filename, lookup_flags, &filepath);
if (error)
goto out;
d_inode(filepath.dentry)
is the same.

This isn't needed as user_path_at() will return ENOTDIR.
Your path as is wuld also preclude AT_EMPTY_PATH with directory file
descriptors and afaict there's various filesystems that seem to support
this on directory inodes.

I'm confused. You're using fdget() above but then you don't use the
resulting file and call user_path_at() instead? Don't bother with
fdget() at all and just call into user_path_at() directly.

Same problem as above. fdget() stuff isn't needed if you're calling
user_path_at() anyway.

Just use the pattern:
error = user_path_at(dfd, filename, lookup_flags, &filepath);
if (error)
return error; /* once you've removed the fdget() direct return works fine */
error = mnt_want_write(filepath.mnt);
