From 6c7d5b48a0e1fd47748e8e83688a3b0a5be4434b Mon Sep 17 00:00:00 2001 From: Javier Cardona Date: Tue, 17 May 2011 16:13:34 -0700 Subject: [PATCH] mac80211: Don't sleep when growing the mesh path After commit a119530dad05c4338cfdc44884ff41a953902e3e (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 Signed-off-by: John W.
