context imbalance false positive sparse warnings

["Steve French" <smfrench@gmail.com>]

Just building one directory of the kernel (./fs/*.c), ie "make bzImage
C=1" generates more than 200 sparse warnings similar to
       warning: context imbalance in 'set_task_ioprio': wrong count at exit

Even the simplest use cases throw this error e.g. fs/super.c line 162-164:

static void put_super(struct super_block *sb)
{
       spin_lock(&sb_lock);
       __put_super(sb);
       spin_unlock(&sb_lock);
}


It doesn't look like sparse has been fixed in a few months, unless the
sparse tool repository has moved from the
    /pub/scm / devel/sparse/sparse.git
directory on git.kernel.org

Is there a way to turn just this warning off (the thousands of context
imbalance messages generated by the kernel build make it harder to see
real errors which sparse could catch)?
