mac80211: Don't sleep when growing the mesh path
After commit 1928ecab620907a0953f811316d05f367f3f4dba (mac80211: fix and simplify mesh locking) mesh table allocation is performed with the pathtbl_resize_lock taken. Under those conditions one should not sleep. This patch makes the allocations GFP_ATOMIC to prevent that. Signed-off-by: Javier Cardona <javier@cozybit.com> Signed-off-by: John W.
