[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>

This reverts commit b3dcad0bfd62fcc9367d8092a71918db53804f53 which is
commit cd4a32e60061789676f7f018a94fcc9ec56732a0 upstream.

Turned out that this should not have been applied to the stable tree.
