Subject: [PATCH 0/6] bonding workqueue and lock rework
Date: Wed, 17 Oct 2007 17:37:44 -0700 [thread overview]
Message-ID: <1192667871139-git-send-email-fubar@us.ibm.com> (raw)
Following are patches to update the locking used in the bonding
driver. This involves two basic changes: conversion from timers to
workqueues for the various periodic monitor functions, and conversion of
locking. These patches should resolve the majority of locking and
might sleep related warnings that occur during certain operations.
The workqueue conversion is fairly straightforward, and
substitutes workqueue driven events for the existing timer driven events.
The locking changes are of two types: first, changes to resolve
deadlocks created by the conversion to workqueues, and second, changes to
make the locking more correct, which generally involves holding RTNL and
no other locks during specific operations. Some of the RTNL-related
changes are fairly extensive, and involve either conditional locking or
releasing and reacquiring locks in order to obey lock ordering
constraints.
These changes were developed and extensively tested by Andy
Gospodarek <andy@greyhouse.net> and myself over the last few months.
Patches are relative to linux-2.6.
