Subject: [PATCH v6 1/7] ARM: kprobes: replace 'union decode_action' to 'struct decode_action'
This patch is generated simply using:
$ sed -i "s/union decode_action/struct decode_action/g" `grep decode_action * -rl`
Which allows futher expansion to decode_action.
Signed-off-by: Wang Nan <wangnan0@...wei.com>
