| |
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.
