2011-03-16nfs: switch NFS from ->get_sb() to ->mount()Al Viro1-66/+66
The last remaining instances of ->get_sb() can be converted ->mount() now - nothing in them uses new vfsmount anymore. Signed-off-by: Al Viro <[email protected]>
2011-03-16nfs: stop mangling ->mnt_devname on NFSAl Viro1-23/+0
now we can do that - nobody cares about its value anymore. Signed-off-by: Al Viro <[email protected]>
2011-03-16vfs: new superblock methods to override /proc/*/mount{s,info}Al Viro3-9/+60
a) ->show_devname(m, mnt) - what to put into devname columns in mounts, mountinfo and mountstats b) ->show_path(m, mnt) - what to put into relative path column in mountinfo Leaving those NULL gives old behaviour. NFS switched to using those. Signed-off-by: Al Viro <[email protected]>

It's always equal to dentry->d_sb Signed-off-by: Al Viro <[email protected]>
2011-03-16nfs: make nfs_path() work without vfsmountAl Viro4-62/+74
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 <[email protected]>
2011-03-16nfs: store devname at disconnected NFS rootsAl Viro3-4/+65
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. Signed-off-by: Al Viro <[email protected]>
2011-03-16nfs: propagate devname to nfs{,4}_get_root()Al Viro3-9/+13
step 1 of ->mnt_devname fixes: make sure we have the value of devname available in ..._get_root(). Signed-off-by: Al Viro <[email protected]>

2011-03-16bonding: enable netpoll without checking link statusAndy Gospodarek1-2/+0
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 Klassert1-0/+2
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 Rajagopalan2-11/+13
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 ? PMSG_THAW : PMSG_RESTORE); dpm_resume_end(cancelled ?

2011-03-16netfilter ebtables: fix xt_AUDIT to work with ebtablesThomas Graf1-9/+27
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. Upon Jan's suggestion, use a separate struct xt_target for NFPROTO_BRIDGE having its own target callback returning EBT_CONTINUE instead of cloning the module.
