130b985 Arnd Bergmann 29 September 2010, 15:47:58 UTC drm: i810/i830: fix locked ioctl variant The i810 and i830 device drivers may replace their file operations on an open file descriptor. My previous patch to move the BKL out of the common DRM code into these drivers only caught the default file operations, not the ones that actually end up being used. Found while trying to come up with a way to kill the BKL for good in these drivers.

9337057 Boaz Harrosh 29 September 2010, 08:34:27 UTC um: Proper Fix for f25c80a4: remove duplicate structure field initialization uml_net_set_mac() was broken and luckily it was never used, before. What it was trying to do is spin_lock before memcopy the mac address. Linus attempted to fix it in assumption that someone decided the lock was needed. But since it was never ever used at all, and was just dead code, I think we can assume that it is not needed, after all. On the other hand patch [f25c80a4] was trying to use eth_mac_addr() in eth_configure(), *which was the real fallout*. Because of state checks done inside eth_mac_addr() the address was never set. I have not reintroduced the memcpy wrapper, but I've put a comment for future cats. The code now is back to exactly as it was before [f25c80a4]. With the cleanup applied. If the spin_lock is indeed needed then a contender should supply a test case that fails, then fix it with the proper locking, as a separate unrelated patch.

When the device is failed to be added, platform_data will be freed by platform_device_put(). But the value saved in platform_data should not be freed here. If it is done, it will make system panic.

8016867 Dave Chinner 24 September 2010, 08:13:44 UTC xfs: force background CIL push under sustained load I have been seeing occasional pauses in transaction throughput up to 30s long under heavy parallel workloads. The only notable thing was that the xfsaild was trying to be active during the pauses, but making no progress. It was running exactly 20 times a second (on the 50ms no-progress backoff), and the number of pushbuf events was constant across this time as well. IOWs, the xfsaild appeared to be stuck on buffers that it could not push out. Further investigation indicated that it was trying to push out inode buffers that were pinned and/or locked. The xfsbufd was also getting woken at the same frequency (by the xfsaild, no doubt) to push out delayed write buffers. The xfsbufd was not making any progress because all the buffers in the delwri queue were pinned. This scan- and-make-no-progress dance went one in the trace for some seconds, before the xfssyncd came along an issued a log force, and then things started going again. However, I noticed something strange about the log force - there were way too many IO's issued. 516 log buffers were written, to be exact. That added up to 129MB of log IO, which got me very interested because it's almost exactly 25% of the size of the log. He delayed logging code is suppose to aggregate the minimum of 25% of the log or 8MB worth of changes before flushing. That's what really puzzled me - why did a log force write 129MB instead of only 8MB? Essentially what has happened is that no CIL pushes had occurred since the previous tail push which cleared out 25% of the log space. That caused all the new transactions to block because there wasn't log space for them, but they kick the xfsaild to push the tail. However, the xfsaild was not making progress because there were buffers it could not lock and flush, and the xfsbufd could not flush them because they were pinned. As a result, both the xfsaild and the xfsbufd could not move the tail of the log forward without the CIL first committing. The cause of the problem was that the background CIL push, which should happen when 8MB of aggregated changes have been committed, is being held off by the concurrent transaction commit load. The background push does a down_write_trylock() which will fail if there is a concurrent transaction commit holding the push lock in read mode. With 8 CPUs all doing transactions as fast as they can, there was enough concurrent transaction commits to hold off the background push until tail-pushing could no longer free log space, and the halt would occur. It should be noted that there is no reason why it would halt at 25% of log space used by a single CIL checkpoint. This bug could definitely violate the "no transaction should be larger than half the log" requirement and hence result in corruption if the system crashed under heavy load. This sort of bug is exactly the reason why delayed logging was tagged as experimental.... The fix is to start blocking background pushes once the threshold has been exceeded. Rework the threshold calculations to keep the amount of log space a CIL checkpoint can use to below that of the AIL push threshold to avoid the problem completely.

e7ee762 Florian Mickler 24 September 2010, 16:22:01 UTC iwl3945: queue the right work if the scan needs to be aborted iwl3945's scan_completed calls into the mac80211 stack which triggers a warn on if there is no scan outstanding. This can be avoided by not calling scan_completed but abort_scan in iwl3945_request_scan in the done: branch of the function which is used as an error out. The done: branch seems to be an error-out branch, as, for example, if iwl_is_ready(priv) returns false the done: branch is executed. NOTE: I'm not familiar with the driver at all. I just quickly scanned as a reaction to https://bugzilla.kernel.org/show_bug.cgi?id=17722 the users of scan_completed in the iwl3945 driver and noted the odd discrepancy between the comment above this instance and the comment in mac80211 scan_completed function.

fad16e7 Tejun Heo 21 September 2010, 07:25:48 UTC ahci: fix module refcount breakage introduced by libahci split libata depends on scsi_host_template for module reference counting and sht's should be owned by each low level driver. During libahci split, the sht was left with libahci.ko leaving the actual low level drivers not reference counted. This made ahci and ahci_platform always unloadable even while they're being actively used. Fix it by defining AHCI_SHT() macro in ahci.h and defining a sht for each low level ahci driver. stable: only applicable to 2.6.35.

This commit fixes the problem. This fix is only a workaround. For a real fix, cpu_sibling_mask() should be defined in UP include code, eg in linux/smp.h, and asm/smp.h should not be included directly. This fix is currently not possible because asm/smp.h defines cpu_sibling_mask() unconditionally and is included directly from many source files.

In particular, putting the device into D3hot is a pretty bad idea when it was already brought up.

2de59fe Will Deacon 27 September 2010, 13:55:15 UTC ARM: 6411/1: vexpress: set RAM latencies to 1 cycle for PL310 on ct-ca9x4 tile The PL310 on the ct-ca9x4 tile for the Versatile Express does not need to add additional latency when accessing its cache RAMs. Unfortunately, the boot monitor sets this up for an 8-cycle delay on reads and writes, resulting in greatly reduced memory performance when the L2 cache is enabled. This patch sets the L2 RAM latencies to the correct value of 1 cycle on the ct-ca9x4 tile before enabling the L2 cache.

00740c5 Borislav Petkov 26 September 2010, 10:42:23 UTC amd64_edac: Fix driver module removal f4347553b30ec66530bfe63c84530afea3803396 removed the edac polling mechanism in favor of using a notifier chain for conveying MCE information to edac. However, the module removal path didn't test whether the driver had setup the polling function workqueue at all and the rmmod process was hanging in the kernel at try_to_del_timer_sync() in the cancel_delayed_work() path, trying to cancel an uninitialized work struct. Fix that by adding a balancing check to the workqueue removal path. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com> 27 September 2010, 10:52:58 UTC

c9e2fbd Alexander Chumachenko 01 April 2010, 12:34:52 UTC x86: Avoid 'constant_test_bit()' misoptimization due to cast to non-volatile While debugging bit_spin_lock() hang, it was tracked down to gcc-4.4 misoptimization of non-inlined constant_test_bit() due to non-volatile addr when 'const volatile unsigned long *addr' cast to 'unsigned long *' with subsequent unconditional jump to pause (and not to the test) leading to hang. Compiling with gcc-4.3 or disabling CONFIG_OPTIMIZE_INLINING yields inlined constant_test_bit() and correct jump, thus working around the kernel bug. Other arches than asm-x86 may implement this slightly differently; 2.6.29 mitigates the misoptimization by changing the function prototype (commit c4295fbb6048d85f0b41c5ced5cbf63f6811c46c) but probably fixing the issue itself is better.

2cc6d2b Neil Horman 24 September 2010, 09:55:52 UTC ipv6: add a missing unregister_pernet_subsys call Clean up a missing exit path in the ipv6 module init routines. In addrconf_init we call ipv6_addr_label_init which calls register_pernet_subsys for the ipv6_addr_label_ops structure. But if module loading fails, or if the ipv6 module is removed, there is no corresponding unregister_pernet_subsys call, which leaves a now-bogus address on the pernet_list, leading to oopses in subsequent registrations. This patch cleans up both the failed load path and the unload path. Tested by myself with good results.
