NFSv4 file locking is currently completely broken since it doesn't respect the OPEN sequencing when it is given an unconfirmed lock_owner and needs to do an open_to_lock_owner. Worse: it breaks the sunrpc rules by doing a GFP_KERNEL allocation inside an rpciod callback. Fix is to preallocate the open seqid structure in nfs4_alloc_lockdata if we see that the lock_owner is unconfirmed. Then, in nfs4_lock_prepare() we wait for either the open_seqid, if the lock_owner is still unconfirmed, or else fall back to waiting on the standard lock_seqid.

Both SLUB and SLAB really did almost exactly the same thing for /proc/slabinfo setup, using duplicate code and per-allocator #ifdef's. This just creates a common CONFIG_SLABINFO that is enabled by both SLUB and SLAB, and shares all the setup code. Maybe SLOB will want this some day too.

A recent bug report: http://bugzilla.kernel.org/show_bug.cgi?id=9674 Was caused because the ULDs now set their own prep functions, but don't necessarily reset the prep function back to the SCSI default when they are removed. This leads to panics if commands are sent to the device after the module is removed because the prep_fn is still pointing to the old module code. The fix for this is to implement a bus remove method that resets the prep_fn pointer correctly before calling the ULD specific driver remove method.

由 Gavin McCullagh 提交于
When a delayed ACK representing two packets arrives, there are two RTT samples available, one for each packet. The first (in order of seq number) will be artificially long due to the delay waiting for the second packet, the second will trigger the ACK and so will not itself be delayed. According to rfc1323, the SRTT used for RTO calculation should use the first rtt, so receivers echo the timestamp from the first packet in the delayed ack. For congestion control however, it seems measuring delayed ack delay is not desirable as it varies independently of congestion. The patch below causes seq_rtt and last_ackt to be updated with any available later packet rtts which should have less (and hopefully zero) delack delay. The rtt value then gets passed to ca_ops->pkts_acked(). Where TCP_CONG_RTT_STAMP was set, effort was made to supress RTTs from within a TSO chunk (!fully_acked), using only the final ACK (which includes any TSO delay) to generate RTTs. This patch removes these checks so RTTs are passed for each ACK to ca_ops->pkts_acked(). For non-delay based congestion control (cubic, h-tcp), rtt is sometimes used for rtt-scaling. In shortening the RTT, this may make them a little less aggressive. Delay-based schemes (eg vegas, veno, illinois) should get a cleaner, more accurate congestion signal, particularly for small cwnds. The congestion control module can potentially also filter out bad RTTs due to the delayed ack alarm by looking at the associated cnt which (where delayed acking is in use) should probably be 1 if the alarm went off or greater if the ACK was triggered by a packet.

We're exporting an __init function, oops :-) The core issue here is that add_preferred_console() is marked as __init, this makes it impossible to invoke this thing from a driver probe routine which is what the Sparc serial drivers need to do. There is no harm in dropping the __init marker. This code will actually work properly when invoked from a modular driver, except that init will probably not pick up the console change without some other support code. Then we can drop the __init from sunserial_console_match() and we're no longer exporting an __init function to modules. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

David Brownell pointed out a regression in my recent "Fix ip command line processing" patch. It turns out to be a fairly blatant oversight on my part whereby ic_enable is never set, and thus autoconfiguration is never enabled. Clearly my testing was broken :-( The solution that I have is to set ic_enable to 1 if we hit ip_auto_config_setup(), which basically means that autoconfiguration is activated unless told otherwise. I then flip ic_enable to 0 if ip=off, ip=none, ip=::::::off or ip=::::::none using ic_proto_name(); The incremental patch is below, let me know if a non-incremental version is prepared, as I did as for the original patch to be reverted pending a fix.

It appears that some PCI-E bridges do the wrong thing in the presense of CRS Software Visibility and MMCONFIG. In particular, it looks like an ATI bridge (device ID 7936) will return 0001 in the vendor ID field of any bridged devices indefinitely. Not enabling CRS SV avoids the problem, and as we currently do not really make good use of the feature anyway (we just time out rather than do any threaded discovery as suggested by the CRS specs), we're better off just not enabling it. This should fix a slew of problem reports with random devices (generally graphics adapters or fairly high-performance networking cards, since it only affected PCI-E) not getting properly recognized on these AMD systems. If we really want to use CRS-SV, we may end up eventually needing a whitelist of systems where this should be enabled, along with some kind of "pcibios_enable_crs()" query to call the system-specific code.
