The filename of the patch is: selftests-mm-fix-the-incorrect-usage-info-of-khugepa.patch and it can be found in the queue-6.11 subdirectory.

If you, or anyone else, feels it should not be added to the stable tree, please let stable@vger.kernel.org know about it.

 [ Upstream commit 3e822bed2fbd1527d88f483342b1d2a468520a9a ]
 
 The mount option of tmpfs should be huge=advise, not madvise which is not
 supported and may mislead the users.
