[PATCH 5.0 05/95] staging: wilc1000: Avoid GFP_KERNEL allocation from atomic context.

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

 



From: Tetsuo Handa <penguin-kernel@xxxxxxxxxxxxxxxxxxx>

commit ae26aa844679cdf660e12c7055f958cb90889eb6 upstream.

Since wilc_set_multicast_list() is called with dev->addr_list_lock
spinlock held, we can't use GFP_KERNEL memory allocation.
