Subject: [PATCH 1/4] drivers/infiniband/hw/qib/qib_iba6120.c: convert GFP_KERNEL to GFP_ATOMIC

From: Julia Lawall <julia.lawall@...6.fr>

The function is called with locks held and thus should not use GFP_KERNEL.

The semantic patch that makes this report is available
in scripts/coccinelle/locks/call_kern.cocci.

More information about semantic patching is available at
http://coccinelle.lip6.fr/

Signed-off-by: Julia Lawall <julia.lawall@...6.fr>
