* [PATCH] inotify: add MOVE_SELF eventJohn McCutchan2005-08-15
| | | | | | | | | | | | | | | | | | | | | This adds a MOVE_SELF event to inotify. It is sent whenever the inode you are watching is moved. We need this event so that we can catch something like this: - app1: watch /etc/mtab - app2: cp /etc/mtab /tmp/mtab-work mv /etc/mtab /etc/mtab~ mv /tmp/mtab-work /etc/mtab app1 still thinks it's watching /etc/mtab but it's actually watching /etc/mtab~.

| * [SCSI] fix target scanning oops with fc transport classJames.Smart@Emulex.Com2005-08-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have some nasty issues with 2.6.12-rc6. Any request to scan on the lpfc or qla2xxx FC adapters will oops. What is happening is the system is defaulting to non-transport registered targets, which inherit the parent of the scan. On this second scan, performed by the attribute, the parent becomes the shost instead of the rport. The slave functions in the 2 FC adapters use starget_to_rport() routines, which incorrectly map the shost as an rport pointer. Additionally, this pointed out other weaknesses: - If the target structure is torn down outside of the transport, we have no method for it to be regenerated at the proper parent. - We have race conditions on the target being allocated by both the midlayer scan (parent=shost) and by the fc transport (parent=rport).

It introduces two new fsnotify calls, that are hooked in at the dcache level. This not only more closely matches how the VFS layer works, it also avoids the problem with locking and inode lifetimes. The two functions are - fsnotify_nameremove -- called when a directory entry is going away. It notifies the PARENT of the deletion. This is called from d_delete(). - inoderemove -- called when the files inode itself is going away. It notifies the inode that is being deleted. This is called from dentry_iput().

* [PATCH] blk: fix tag shrinking (revive real_max_size)Tejun Heo2005-08-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | My patch in commit fa72b903f75e4f0f0b2c2feed093005167da4023 incorrectly removed blk_queue_tag->real_max_depth. The original resize implementation was incorrect in the following points. * actual allocation size of tag_index was shorter than real_max_size, but assumed to be of the same size, possibly causing memory access beyond the allocated area. * bits in tag_map between max_deptn and real_max_depth were initialized to 1's, making the tags permanently reserved. In an attempt to fix above two bugs, I had removed allocation optimization in init_tag_map and real_max_size. Tag map/index were allocated and freed immediately during resize. Unfortunately, I wasn't considering that tag map/index can be resized dynamically with tags beyond new_depth active. This led to accessing freed area after shrinking tags and led to the following bug reporting thread on linux-scsi. http://marc.theaimsgroup.com/?l=linux-scsi&m=112319898111885&w=2 To fix the problem, I've revived real_max_depth without allocation optimization in init_tag_map, and Andrew Vasquez confirmed that the problem was fixed. As Jens is not going to be available for a week, he asked me to make sure that this patch reaches you. http://marc.theaimsgroup.com/?l=linux-scsi&m=112325778530886&w=2 Also, a comment was added to make sure that real_max_size is needed for dynamic shrinking.

* [PATCH] pci and yenta: pcibios_bus_to_resourceDominik Brodowski2005-08-05
| | | | | | | | | | | | | | | In yenta_socket, we default to using the resource setting of the CardBus bridge. However, this is a PCI-bus-centric view of resources and thus needs to be converted to generic resources first. Therefore, add a call to pcibios_bus_to_resource() call in between. This function is a mere wrapper on x86 and friends, however on some others it already exists, is added in this patch (alpha, arm, ppc, ppc64) or still needs to be provided (parisc -- where is its pcibios_resource_to_bus() ?).

* [PATCH] PCI: restore BAR values after D3hot->D0 for devices that need itJohn W. Linville2005-08-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some PCI devices (e.g. 3c905B, 3c556B) lose all configuration (including BARs) when transitioning from D3hot->D0. This leaves such a device in an inaccessible state. The patch below causes the BARs to be restored when enabling such a device, so that its driver will be able to access it. The patch also adds pci_restore_bars as a new global symbol, and adds a correpsonding EXPORT_SYMBOL_GPL for that. Some firmware (e.g. Thinkpad T21) leaves devices in D3hot after a (re)boot. Most drivers call pci_enable_device very early, so devices left in D3hot that lose configuration during the D3hot->D0 transition will be inaccessible to their drivers. Drivers could be modified to account for this, but it would be difficult to know which drivers need modification. This is especially true since often many devices are covered by the same driver. It likely would be necessary to replicate code across dozens of drivers. The patch below should trigger only when transitioning from D3hot->D0 (or at boot), and only for devices that have the "no soft reset" bit cleared in the PM control register. I believe it is safe to include this patch as part of the PCI infrastructure. The cleanest implementation of pci_restore_bars was to call pci_update_resource. Unfortunately, that does not currently exist for the sparc64 architecture. The patch below includes a null implemenation of pci_update_resource for sparc64. Some have expressed interest in making general use of the the pci_restore_bars function, so that has been exported to GPL licensed modules. Signed-off-by: John W.

* [PATCH] fix get_user_pages bugNick Piggin2005-08-03
| | | | | | | | | | | | | | | | | | | | | | | Checking pte_dirty instead of pte_write in __follow_page is problematic for s390, and for copy_one_pte which leaves dirty when clearing write. So revert __follow_page to check pte_write as before, and make do_wp_page pass back a special extra VM_FAULT_WRITE bit to say it has done its full job: once get_user_pages receives this value, it no longer requires pte_write in __follow_page. But most callers of handle_mm_fault, in the various architectures, have switch statements which do not expect this new case. To avoid changing them all in a hurry, make an inline wrapper function (using the old name) that masks off the new bit, and use the extended interface with double underscores. Yes, we do have a call to do_wp_page from do_swap_page, but no need to change that: in rare case it's needed, another do_wp_page will follow.

* [PATCH] increase PCIBIOS_MIN_IO on x86Ivan Kokshaysky2005-08-02
| | | | | | | | | | | | | | | | There is a number of x86 laptops that have some non-PCI IO ports in the 0x1000-0x1fff range, and it's quite hard to control the correct order of resource allocation between PCI and other subsystems controlling these ports. Especially with modular kernel. So just increase PCIBIOS_MIN_IO to 0x4000 to prevent any new PCI resource allocations in the problematic range (this limitation must apply _only_ to the root bus resources - see Linus' change in pci_bus_alloc_resource). As PCIBIOS_MIN_IO and PCIBIOS_MIN_CARDBUS_IO are the same now on i386 and x86-64, we can remove the latter.

* | | [PATCH] Fix sync_tsc hangEric W. Biederman2005-07-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sync_tsc was using smp_call_function to ask the boot processor to report it's tsc value. smp_call_function performs an IPI_send_allbutself which is a broadcast ipi. There is a window during processor startup during which the target cpu has started and before it has initialized it's interrupt vectors so it can properly process an interrupt. Receveing an interrupt during that window will triple fault the cpu and do other nasty things. Why cli does not protect us from that is beyond me. The simple fix is to match ia64 and provide a smp_call_function_single. Which avoids the broadcast and is more efficient. This certainly fixes the problem of getting stuck on boot which was very easy to trigger on my SMP Hyperthreaded Xeon, and I think it fixes it for the right reasons.
