Subject: [PATCH 00/11] Enhancements and bugfixes to PCI hotplug subsystem
Date: Fri, 23 Mar 2012 22:58:16 +0800 [thread overview]
Message-ID: <1332514707-9673-1-git-send-email-jiang.liu@huawei.com> (raw)
This is a series of RFC patches, to make sure we are doing the
right thing in the right way. The patchset hasn't been tested yet.
There are several minor bugfixes and two proposals.
The first proposal is to add notification chain for PCI hotplug events,
so other components interested in PCI root/bus/device hotplug events
could subscribe to the chain.
The second prososal is to introduce a recursive mutex lock to
serialize all hotplug operations triggered by sysfs interfaces,
PCI HPC hardware events, ACPI hotplug events and other sources.
There are still works left in driver/pci/hotplug directory to apply
the above two proposals.
The patchset applies to Yinghai's work on PCI root bus hotplug at
git://git.kernel.org/pub/scm/linux/kernel/git/yinghai/linux-yinghai.git for-x86-irq
And it depends on my previous patchset, please refer to
http://www.spinics.net/lists/linux-pci/msg14472.html
Thanks!
