Subject: timekeeping: Cast raw_interval to u64 to avoid shift overflow
From: Dan Carpenter <[email protected]>
commit 5b3900cd409466c0070b234d941650685ad0c791 upstream.
We fixed a bunch of integer overflows in timekeeping code during the 3.6
cycle. I did an audit based on that and found this potential overflow.
