Subject: [PATCH 0/2] firmware loader: avoid blocking suspend by !uevent requests
Date: Mon, 27 May 2013 18:30:02 +0800	[thread overview]
Message-ID: <1369650604-27941-1-git-send-email-ming.lei@canonical.com> (raw)

Hi,

Recently, Takashi reported that requests with FW_ACTION_NOHOTPLUG may block
shutdown and fixed that by killing pending requests before shutdown. But
these requests still may block suspend, so the 2 patches is introduced to
fix the problem during suspend.

The 2nd patch depends on Takashi Iwai's patch of "firmware: Avoid deadlock of
usermodehelper lock at shutdown".

Thanks,
