2011-03-16nfs: make nfs_path() work without vfsmountAl Viro
part 3: now we have everything to get nfs_path() just by dentry - just follow to (disconnected) root and pick the rest of the thing there. Start killing propagation of struct vfsmount * on the paths that used to bring it to nfs_path(). Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-03-16nfs: store devname at disconnected NFS rootsAl Viro
part 2: make sure that disconnected roots have corresponding mnt_devname values stashed into them. Have nfs*_get_root() stuff a copy of devname into ->d_fsdata of the found root, provided that it is disconnected. Have ->d_release() free it when dentry goes away. Have the places where NFS uses ->d_fsdata for sillyrename (and that can *never* happen to a disconnected root - dentry will be attached to its parent) free old devname copies if they find those.

2011-03-16nfs: propagate devname to nfs{,4}_get_root()Al Viro

2011-03-16bonding: enable netpoll without checking link statusAndy Gospodarek
Only slaves that are up should transmit netpoll frames, so there is no need to check to see if a slave is up before enabling netpoll on it. This resolves a reported failure on active-backup bonds where a slave interface is down when netpoll was enabled.

2011-03-16xfrm: Refcount destination entry on xfrm_lookupSteffen Klassert
We return a destination entry without refcount if a socket policy is found in xfrm_lookup. This triggers a warning on a negative refcount when freeeing this dst entry. So take a refcount in this case to fix it. This refcount was forgotten when xfrm changed to cache bundles instead of policies for outgoing flows.

2011-03-16xen: use freeze/restore/thaw PM events for suspend/resume/chkptShriram Rajagopalan
Use PM_FREEZE, PM_THAW and PM_RESTORE power events for suspend/resume/checkpoint functionality, instead of PM_SUSPEND and PM_RESUME. Use of these pm events fixes the Xen Guest hangup when taking checkpoints. When a suspend event is cancelled (while taking checkpoints once/continuously), we use PM_THAW instead of PM_RESUME. PM_RESTORE is used when suspend is not cancelled. See Documentation/power/devices.txt and linux/pm.h for more info about freeze, thaw and restore. The sequence of pm events in a suspend-resume scenario is shown below. dpm_suspend_start(PMSG_FREEZE); dpm_suspend_noirq(PMSG_FREEZE); sysdev_suspend(PMSG_FREEZE); cancelled = suspend_hypercall() sysdev_resume(); dpm_resume_noirq(cancelled ?

2011-03-16netfilter ebtables: fix xt_AUDIT to work with ebtablesThomas Graf
Even though ebtables uses xtables it still requires targets to return EBT_CONTINUE instead of XT_CONTINUE. This prevented xt_AUDIT to work as ebt module.
