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

 



From: Takashi Iwai <tiwai@xxxxxxx>

This patch has been added to the 4.1 stable tree. If you have any
objections, please let us know.

===============

[ Upstream commit 3a72494ac2a3bd229db941d51e7efe2f6ccd947b ]

The timer user status compat ioctl returned the bogus struct used for
64bit architectures instead of the 32bit one.  This patch addresses
it to return the proper struct.
