Message-ID: <20120904162137.GA11841@elgon.mountain> (raw)
Hello Szymon Janc,
The patch 7cfeb868eb85: "Bluetooth: Use GFP_KERNEL in
read_index_list" from Aug 31, 2012, leads to the following warning:
net/bluetooth/mgmt.c:343 read_index_list()
error: scheduling with locks held: 'read_lock:hci_dev_list_lock'
This patch should be reverted because we're not allowed to schedule
while holding the read lock. The way to avoid these bugs in the future
is to test with CONFIG_DEBUG_ATOMIC_SLEEP=y. It will give a big splat.
regards,
dan carpenter
