[139/152] mv_xor: fix race in tasklet function

From: Greg KH
Date: Wed Jan 05 2011 - 19:35:31 EST

2.6.36-stable review patch. If anyone has any objections, please let us know.


From: Saeed Bishara <saeed@xxxxxxxxxxx>

commit 8333f65ef094e47020cd01452b4637e7daf5a77f upstream.

use mv_xor_slot_cleanup() instead of __mv_xor_slot_cleanup() as the former function
aquires the spin lock that needed to protect the drivers data.
