[Devel] [PATCH hci-8.1 v4 07/11] dm-ploop: take bat_lock around md page lookup in ploop_llseek_hole()

[no-reply at sashiko.virtuozzo.com]

> ploop_llseek_hole() walks the md pages tree without any lock, while
> resize inserts new md pages into it in ploop_add_md_pages(). A lookup
> racing with rb-tree rebalancing may follow a stale pointer or miss the
> page and return -EINVAL.
