| |
2.6.37-stable review patch. If anyone has any objections, please let us know.
------------------
From: =?UTF-8?q?Timo=20Ter=C3=A4s?= <timo.teras@iki.fi>
commit d70c673153d42e8aefd5ac296c8159ef222d076b upstream.
The channel callbacks are called directly from vmbus_event_dpc which runs in tasklet context. These callbacks need to use GFP_ATOMIC.
