From: Kangjie Lu <kangji...@gmail.com> 3.12-stable review patch. If anyone has any objections, please let me know.
=============== commit e4ec8cc8039a7063e24204299b462bd1383184a5 upstream. The stack object “r1” has a total size of 32 bytes. Its field “event” and “val” both contain 4 bytes padding. These 8 bytes padding bytes are sent to user without being initialized.
