commit 9df6a4870dc371136e90330cfbbc51464ee66993 upstream.
When integrity_inode_get() is querying and inserting the cache, there
is a conditional race in the concurrent environment.
The race condition is the result of not properly implementing
"double-checked locking". In this case, it first checks to see if the
iint cache record exists before taking the lock, but doesn't check
again after taking the integrity_iint_lock.
