2011-03-15fs: Remove i_nlink check from file system link callbackAneesh Kumar K.V6-42/+0
Now that VFS check for inode->i_nlink == 0 and returns proper error, remove similar check from file system Signed-off-by: Aneesh Kumar K.V <[email protected]> Signed-off-by: Al Viro <[email protected]>
2011-03-15fs: Don't allow to create hardlink for deleted fileAneesh Kumar K.V1-1/+5
Add inode->i_nlink == 0 check in VFS. Some of the file systems do this internally. A followup patch will remove those instance. This is needed to ensure that with link by handle we don't allow to create hardlink of an unlinked file. The check also prevent a race between unlink and link Signed-off-by: Aneesh Kumar K.V <[email protected]> Signed-off-by: Al Viro <[email protected]>

Hardware timestamping for Intel 82580 didn't work in either 2.6.36 or 2.6.37. Comparing it to Intel's igb-2.4.12 I found that the timecounter_init clock/counter initialization was done too early.

2011-03-15IPVS: Conditionally define and use ip_vs_lblc{r}_tableSimon Horman2-9/+20
ip_vs_lblc_table and ip_vs_lblcr_table, and code that uses them are unnecessary when CONFIG_SYSCTL is undefined. Signed-off-by: Simon Horman <[email protected]>
2011-03-15IPVS: Minimise ip_vs_leave when CONFIG_SYSCTL is undefinedSimon Horman1-2/+7
Much of ip_vs_leave() is unnecessary if CONFIG_SYSCTL is undefined. I tried an approach of breaking the now #ifdef'ed portions out into a separate function. However this appeared to grow the compiled code on x86_64 by about 200 bytes in the case where CONFIG_SYSCTL is defined. So I have gone with the simpler though less elegant #ifdef'ed solution for now. Signed-off-by: Simon Horman <[email protected]>

2011-03-15ipvs: optimize rates readingJulian Anastasov3-39/+27
Move the estimator reading from estimation_timer to user context. ip_vs_read_estimator() will be used to decode the rate values. As the decoded rates are not set by estimation timer there is no need to reset them in ip_vs_zero_stats. There is no need ip_vs_new_estimator() to encode stats to rates, if the destination is in trash both the stats and the rates are inactive.

2011-03-15ipvs: properly zero stats and ratesJulian Anastasov3-43/+69
Currently, the new percpu counters are not zeroed and the zero commands do not work as expected, we still show the old sum of percpu values. OTOH, we can not reset the percpu counters from user context without causing the incrementing to use old and bogus values. So, as Eric Dumazet suggested fix that by moving all overhead to stats reading in user context. Do not introduce overhead in timer context (estimator) and incrementing (packet handling in softirqs). The new ustats0 field holds the zero point for all counter values, the rates always use 0 as base value as before. When showing the values to user space just give the difference between counters and the base values. The only drawback is that percpu stats are not zeroed, they are accessible only from /proc and are new interface, so it should not be a compatibility problem as long as the sum stats are correct after zeroing.

2011-03-15ipvs: reorganize tot_statsJulian Anastasov4-28/+29
The global tot_stats contains cpustats field just like the stats for dest and svc, so better use it to simplify the usage in estimation_timer. As tot_stats is registered as estimator we can remove the special ip_vs_read_cpu_stats call for tot_stats. Fix ip_vs_read_cpu_stats to be called under stats lock because it is still used as synchronization between estimation timer and user context (the stats readers). Also, make sure ip_vs_stats_percpu_show reads properly the u64 stats from user context.

2011-03-15ipvs: move struct netns_ipvsJulian Anastasov3-144/+123
Remove include/net/netns/ip_vs.h because it depends on structures from include/net/ip_vs.h. As ipvs is pointer in struct net it is better to move struct netns_ipvs into include/net/ip_vs.h, so that we can easily use other structures in struct netns_ipvs. Signed-off-by: Julian Anastasov <[email protected]> Signed-off-by: Simon Horman <[email protected]>

2011-03-14macvlan : fix checksums error when we are in bridge modeDaniel Lezcano1-0/+3
When the lower device has offloading capabilities, the packets checksums are not computed. That leads to have any macvlan port in bridge mode to not work because the packets are dropped due to a bad checksum. If the macvlan is in bridge mode, the packet is forwarded to another macvlan port and reach the network stack where it looks for a checksum but this one was not computed due to the offloading of the lower device. In this case, we have to set the packet with CHECKSUM_UNNECESSARY when it is forwarded to a bridged port and restore the previous value of ip_summed when the packet goes to the lowerdev.

2011-03-15PM / Hibernate: Reduce autotuned default image sizeRafael J. Wysocki1-4/+4
The hibernate image size autotuning mechanism sets the default image size to 5/2 of the total system RAM, but it is reported that on some systems device drivers allocate substantial amounts of memory during suspend and the creation of the image fails as a result (too little memory is preallocated). Modify the autotuning mechanism to use 1/3 instead of 2/5 of RAM as the default image size, which is reported to be sufficient for the affected systems.

2011-03-15PM / Core: Introduce struct syscore_ops for core subsystems PMRafael J. Wysocki6-1/+164
Some subsystems need to carry out suspend/resume and shutdown operations with one CPU on-line and interrupts disabled. The only way to register such operations is to define a sysdev class and a sysdev specifically for this purpose which is cumbersome and inefficient. Moreover, the arguments taken by sysdev suspend, resume and shutdown callbacks are practically never necessary. For this reason, introduce a simpler interface allowing subsystems to register operations to be executed very late during system suspend and shutdown and very early during resume in the form of strcut syscore_ops objects.

I have a machine where entering deep C-states broke. pm_qos was a hot candidate, but I couldn't find any way to double check without the need of recompiling. While in this case it was a driver bug (ath9k): https://bugzilla.kernel.org/show_bug.cgi?id=27532 powertop or others may want to read out cpu_dma_latency restrictions which could be the cause of preventing a machine entering deeper C-states.

2011-03-15PM: Make system-wide PM and runtime PM treat subsystems consistentlyRafael J. Wysocki4-118/+92
The code handling system-wide power transitions (eg. suspend-to-RAM) can in theory execute callbacks provided by the device's bus type, device type and class in each phase of the power transition. In turn, the runtime PM core code only calls one of those callbacks at a time, preferring bus type callbacks to device type or class callbacks and device type callbacks to class callbacks. It seems reasonable to make them both behave in the same way in that respect. Moreover, even though a device may belong to two subsystems (eg. bus type and device class) simultaneously, in practice power management callbacks for system-wide power transitions are always provided by only one of them (ie. if the bus type callbacks are defined, the device class ones are not and vice versa). Thus it is possible to modify the code handling system-wide power transitions so that it follows the core runtime PM code (ie. treats the subsystem callbacks as mutually exclusive). On the other hand, the core runtime PM code will choose to execute, for example, a runtime suspend callback provided by the device type even if the bus type's struct dev_pm_ops object exists, but the runtime_suspend pointer in it happens to be NULL. This is confusing, because it may lead to the execution of callbacks from different subsystems during different operations (eg. the bus type suspend callback may be executed during runtime suspend of the device, while the device type callback will be executed during system suspend). Make all of the power management code treat subsystem callbacks in a consistent way, such that: (1) If the device's type is defined (eg. dev->type is not NULL) and its pm pointer is not NULL, the callbacks from dev->type->pm will be used. (2) If dev->type is NULL or dev->type->pm is NULL, but the device's class is defined (eg. dev->class is not NULL) and its pm pointer is not NULL, the callbacks from dev->class->pm will be used. (3) If dev->type is NULL or dev->type->pm is NULL and dev->class is NULL or dev->class->pm is NULL, the callbacks from dev->bus->pm will be used provided that both dev->bus and dev->bus->pm are not NULL.
