* Kill CL_PROPAGATION, sanitize fs/pnode.c:get_source()Al Viro2010-03-033-14/+19
| | | | | | | | | | | | | | | | First of all, get_source() never results in CL_PROPAGATION alone. We either get CL_MAKE_SHARED (for the continuation of peer group) or CL_SLAVE (slave that is not shared) or both (beginning of peer group among slaves). Massage the code to make that explicit, kill CL_PROPAGATION test in clone_mnt() (nothing sets CL_MAKE_SHARED without CL_PROPAGATION and in clone_mnt() we are checking CL_PROPAGATION after we'd found that there's no CL_SLAVE, so the check for CL_MAKE_SHARED would do just as well).

* fs: improve remount,ro vs buffercache coherencyNick Piggin2010-03-031-3/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Invalidate sb->s_bdev on remount,ro. Fixes a problem reported by Jorge Boncompte who is seeing corruption trying to snapshot a minix filesystem image. Some filesystems modify their metadata via a path other than the bdev buffer cache (eg. they may use a private linear mapping for their metadata, or implement directories in pagecache, etc). Also, file data modifications usually go to the bdev via their own mappings. These updates are not coherent with buffercache IO (eg. via /dev/bdev) and never have been. However there could be a reasonable expectation that after a mount -oremount,ro operation then the buffercache should subsequently be coherent with previous filesystem modifications. So invalidate the bdev mappings on a remount,ro operation to provide a coherency point. The problem was exposed when we switched the old rd to brd because old rd didn't really function like a normal block device and updates to rd via mappings other than the buffercache would still end up going into its buffercache. But the same problem has always affected other "normal" block devices, including loop.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Traffic (tcp) doesnot start on a vlan interface when gro is enabled. Even the tcp handshake was not taking place. This is because, the eth_type_trans call before the netif_receive_skb in napi_gro_finish() resets the skb->dev to napi->dev from the previously set vlan netdev interface. This causes the ip_route_input to drop the incoming packet considering it as a packet coming from a martian source. I could repro this on 2.6.32.7 (stable) and 2.6.33-rc7. With this fix, the traffic starts and the test runs fine on both vlan and non-vlan interfaces.

However, iwl_set_rxon_ht was being called before iwl_set_rxon_channel and thus HT40 could be broken unless another call to iwl_mac_config came in. This problem was recently introduced by "iwlwifi: Fix to set correct ht configuration" The particular setting in which I noticed this was monitor mode: iwconfig wlan0 mode monitor ifconfig wlan0 up ./iw wlan0 set channel 64 HT40- #./iw wlan0 set channel 64 HT40- tcpdump -i wlan0 -y IEEE802_11_RADIO would only catch HT40 packets if I issued the IW command twice. From visual inspection, iwl_set_rxon_channel does not depend on iwl_set_rxon_ht, so simply swapping them should be safe and fixes this problem.

So Unconditional call to the netif_wake_queue() here is wrong. This might cause calling of start_xmit routine on txfull state and trigger BUG_ON. This bug does not happen when NAPI disabled. After txdone there must be at least one free tx slot. But with NAPI, this is not true anymore and the BUG_ON can hits on heavy load. In this driver NAPI was enabled on 2.6.33-rc1 so this is regression from 2.6.32 kernel.

Unfortunately, it seems that with Thomas Renninger's patch last July to eliminate _PPC evaluations when the processor driver loads, the kernel never actually reads _PPC at all! This is problematic if you happen to boot your non-T60 computer in a state where the BIOS _wants_ _PPC to be something other than zero. So, put the _PPC evaluation back into acpi_processor_get_performance_info if ignore_ppc isn't 1. Signed-off-by: Darrick J. Wong <djwong@us.ibm.com> Signed-off-by: Len Brown <len.brown@intel.com>

Only mwait based C1 was using the write to the monitored address to wake up mwait'ing CPU. This patch changes the code to retain TS_POLLING bit if we are entering an mwait based deep C-state. The patch has been verified to reduce the number of resched IPIs in general and also improves the performance/power on workloads with low system utilization (i.e., when mwait based deep C-states are being used).

It was likely masking a bug elsewhere that's since been fixed. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

I presume that filling multiple PTEs identically with length flags and the physical address of the start of a block of VRAM is a hint to the memory controller that it need not perform additional page table lookups for that range of addresses.
