This patch adds behavioural changes:
- if (j->read_buffer) {
- kfree(j->read_buffer);
- j->read_buffer = NULL;
- j->read_buffer_size = 0;
- }
+ j->read_buffer = NULL;
+ j->read_buffer_size = 0;
Now we'll zero ->read_buffer_size even if ->read_buffer was already NULL.
It's hard to believe that this could cause any problems, but please check
that.
