2011-03-17vfs: split off vfsmount-related parts of vfs_kern_mount()Al Viro3-122/+132
new function: mount_fs(). Does all work done by vfs_kern_mount() except the allocation and filling of vfsmount; returns root dentry or ERR_PTR(). vfs_kern_mount() switched to using it and taken to fs/namespace.c, along with its wrappers. alloc_vfsmnt()/free_vfsmnt() made static. functions in namespace.c slightly reordered.

2011-03-17Some fixes for pstoreTony Luck1-60/+56
1) Change from ->get_sb() to ->mount() 2) Use mount_single() instead of mount_nodev() 3) Pulled in ramfs_get_inode() & trimmed to what I need for pstore 4) Drop the ugly pstore_writefile() Just save data using kmalloc() and provide a pstore_file_read() that uses simple_read_from_buffer().

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 <viro@zeniv.linux.org.uk>

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 <viro@zeniv.linux.org.uk>
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.

2011-03-16Increase OSF partition limit from 8 to 18Linus Torvalds1-1/+1
It turns out that while a maximum of 8 partitions may be what people "should" have had, you can actually fit up to 18 entries(*) in a sector. And some people clearly were taking advantage of that, like Michael Cree, who had ten partitions on one of his OSF disks. (*) The OSF partition data starts at byte offset 64 in the first sector, and the array of 16-byte partition entries start at offset 148 in the on-disk partition structure.

2011-03-16prune back iprune_semChristoph Hellwig1-18/+14
iprune_sem is continously giving us lockdep warnings because we do take it in read mode in the reclaim path, but we're also doing non-NOFS allocations under it taken in write mode. Taking a bit deeper look at it I think it's fixable quite trivially: - for invalidate_inodes we do not need iprune_sem at all. We have an active reference on the superblock, so the filesystem is not going away until it has finished. - for evict_inodes we do need it, to make sure prune_icache has done it's work before we tear down the superblock. But there is no reason to hold it over the actual reclaim operation - it's enough to cycle through it after the actual reclaim to make sure we wait for any pending prune_icache to complete. We just have to remove the WARN_ON for otherwise busy inodes as they can actually happen now. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2011-03-16x86, AMD: Set ARAT feature on AMD processorsBoris Ostrovsky1-0/+4
Support for Always Running APIC timer (ARAT) was introduced in commit db954b5898dd3ef3ef93f4144158ea8f97deb058. This feature allows us to avoid switching timers from LAPIC to something else (e.g. HPET) and go into timer broadcasts when entering deep C-states. AMD processors don't provide a CPUID bit for that feature but they also keep APIC timers running in deep C-states (except for cases when the processor is affected by erratum 400). Therefore we should set ARAT feature bit on AMD CPUs.

2011-03-15xen network backend driverIan Campbell9-54/+2908
netback is the host side counterpart to the frontend driver in drivers/net/xen-netfront.c. The PV protocol is also implemented by frontend drivers in other OSes too, such as the BSDs and even Windows. The patch is based on the driver from the xen.git pvops kernel tree but has been put through the checkpatch.pl wringer plus several manual cleanup passes and review iterations. The driver has been moved from drivers/xen/netback to drivers/net/xen-netback. One major change from xen.git is that the guest transmit path (i.e. what looks like receive to netback) has been significantly reworked to remove the dependency on the out of tree PageForeign page flag (a core kernel patch which enables a per page destructor callback on the final put_page). This page flag was used in order to implement a grant map based transmit path (where guest pages are mapped directly into SKB frags). Instead this version of netback uses grant copy operations into regular memory belonging to the backend domain. Reinstating the grant map functionality is something which I would like to revisit in the future. Note that this driver depends on 2e820f58f7ad "xen/irq: implement bind_interdomain_evtchn_to_irqhandler for backend drivers" which is in linux next via the "xen-two" tree and is intended for the 2.6.39 merge window: git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git stable/backends this branch has only that single commit since 2.6.38-rc2 and is safe for cross merging into the net branch.

2011-03-15bonding: Improve syslog message at device creation timePhil Oester1-1/+4
When the bonding module is loaded, it creates bond0 by default. Then, when attempting to create bond0, the following messages are printed to syslog: kernel: bonding: bond0 is being created... kernel: bonding: Bond creation failed. Which seems to indicate a problem, when in reality there is no problem. Since the actual error code is passed down from bond_create, make use of it to print a bit less ominous message: kernel: bonding: bond0 is being created... kernel: bond0 already exists.

2011-03-15bonding: Call netif_carrier_off after register_netdevicePhil Oester1-2/+2
Bringing up a bond interface with all network cables disconnected does not properly set the interface as DOWN because the call to netif_carrier_off occurs too early in bond_init. The call needs to occur after register_netdevice has set dev->reg_state to NETREG_REGISTERED, so that netif_carrier_off will trigger the call to linkwatch_fire_event.

2011-03-15bonding: Incorrect TX queue offsetPhil Oester1-2/+9
When packets come in from a device with >= 16 receive queues headed out a bonding interface, syslog gets filled with this: kernel: bond0 selects TX queue 16, but real number of TX queues is 16 because queue_mapping is offset by 1. Adjust return value to account for the offset. This is a revision of my earlier patch (which did not use the skb_rx_queue_* helpers - thanks to Ben for the suggestion). Andy submitted a similar patch which emits a pr_warning on invalid queue selection, but I believe the log spew is not useful. We can revisit that question in the future, but in the interim I believe fixing the core problem is worthwhile.
