Subject: [PATCH v3 0/2] Fix syzkaller bug: hung task in hub_port_init
Date: Fri, 13 Aug 2021 23:55:06 +0530	[thread overview]
Message-ID: <20210813182508.28127-1-mail@anirudhrb.com> (raw)

This series fixes the hung task bug in hub_port_init reported by
syzkaller at:

https://syzkaller.appspot.com/bug?id=08f12df95ae7da69814e64eb5515d5a85ed06b76

The first patch in the series fixes the issue and the second patch does
some refactoring to avoid duplicate code.

Changes in v3:
- Split the patch into two patches
- Remove the convenience wrappers as suggested by Shuah
- Remove the WARN as suggested by Greg

Changes in v2:
Use WARN_ON() instead of BUG() when unlink_list is neither unlink_tx nor
unlink_rx.
v2: https://lore.kernel.org/lkml/20210806181335.2078-1-mail@anirudhrb.com/

v1: https://lore.kernel.org/lkml/20210806164015.25263-1-mail@anirudhrb.com/
