- Initialize all non mutually exclusive variables without regard to the mode selected. - Do a software reset each time the parameters are set, regardless of whether anything changes. This may allow an application to recover from a hung condition. - Improved error reporting. - Removed $Id:$ Signed-off-by:

The following patch prevents the crash dump helper code found within kexec from breaking ppc which still lacks crash dump functionality. ksysfs crash_notes attribute handling was left under CONFIG_KEXEC for simplicity although it is not strictly kexec related. We provide here a dummy definition for crash_notes on ppc. Signed-off-by:

While fixing an oops in the st driver in a dirty release path, I encountered an oops in cdev_put for cdevs allocated using cdev_alloc. If cdev_del is called when the cdev kobject still has an open user, when the last cdev_put is called, the cdev_put will call kobject_put, which will end up ultimately releasing the cdev in cdev_dynamic_release. Patch fixes the oops by preventing cdev_put from accessing freed memory. Signed-off-by:

When a noninitial thread does exec, it becomes the new group leader. If there is a ITIMER_REAL timer running, it points at the old group leader and when it fires it can follow a stale pointer. The timer data needs to be reset to point at the exec'ing thread that is becoming the group leader. This has to synchronize with any concurrent firing of the timer to make sure that it_real_fn can never run when the data points to a thread that might have been reaped already. Signed-off-by:

This patch fixes a fairly serious tlb flushing bug that makes aio use under uml very unreliable -- SEGVs, Oops and panic()s occur as a result of stale tlb entires being used by uml when aio switches mms due to the fact that uml does not implement the activate_mm() hook. This patch introduces a simple but correct approach (read: hammer) for implementing activate_mm() in uml by doing a force_flush_all() if the new mm is different from old. With this patch in place, uml is able to succeed at the aio test case that was randomly faulting for me before. Cc: Jeff Dike <jdike@addtoit.com> Cc: <blaisorblade@yahoo.it> Signed-off-by:

mm/filemap_xip.c: In function `__xip_unmap': mm/filemap_xip.c:194: request for member `pte' in something not a structure or union Apparently pte_pfn() takes a pte_t, not a pointer to a pte_t. From looking at asm/page.h, it seems to be the same on ia32 or ppc (iff STRICT_MM_TYPECHECKS is enabled, which is disabled by default on ppc). Acked-by:

The current CardBus window allocation code in yenta_socket is unable to handle the transparent PCI-bridge handling update in 2.6.13. We need to check _all_ resources of a given type to find the best one suitable for CardBus windows, not just the first one. Signed-off-by:

Dominik Brodowski authored
If the CardBus windows were pre-configured and the CardBus bridge is behind a transparent PCI-PCI bridge, pci_find_parent_resource() might return a different resource than the real parent if it is called before the window is determined. Therefore, move that call around. Also fix return of value in void function. Signed-off-by:

Bug symptoms ~~~~~~~~~~~~ For the same inode VFS calls read_inode() twice and doesn't call clear_inode() between the two read_inode() invocations. Bug description ~~~~~~~~~~~~~~~ Suppose we have an inode which has zero reference count but is still in the inode cache. Suppose kswapd invokes shrink_icache_memory() to free some RAM. In prune_icache() inodes are removed from i_hash. prune_icache () is then going to call clear_inode(), but drops the inode_lock spinlock before this. If in this moment another task calls iget() for an inode which was just removed from i_hash by prune_icache(), then iget() invokes read_inode() for this inode, because it is *already removed* from i_hash. The end result is: we call iget(#N) then iput(#N); inode #N has zero i_count now and is in the inode cache; kswapd starts. kswapd removes the inode #N from i_hash ans is preempted; we call iget(#N) again; read_inode() is invoked as the result; but we expect clear_inode() before. Fix ~~~~~~~ To fix the bug I remove inodes from i_hash later, when clear_inode() is actually called. I remove them from i_hash under spinlock protection. Since the i_state is set to I_FREEING, it is safe to do this. The others will sleep waiting for the inode state change. I also postpone removing inodes from i_sb_list. It is not compulsory to do so but I do it for readability reasons. Inodes are added/removed to the lists together everywhere in the code and there is no point to change this rule. This is harmless because the only user of i_sb_list which somehow may interfere with me (invalidate_list()) is excluded by the iprune_sem mutex. The same race is possible in invalidate_list() so I do the same for it. Acked-by:

This patch fixes queer behavior in __wait_on_freeing_inode(). If I_LOCK was not set it called yield(), effectively busy waiting for the removal of the inode from the hash. This change was introduced within "[PATCH] eliminate inode waitqueue hashtable" Changeset 1.1938.166.16 last october by wli. The solution is to restore the old behavior, of unconditionally waiting on the waitqueue. It doesn't matter if I_LOCK is not set initally, the task will go to sleep, and wake up when wake_up_inode() is called from generic_delete_inode() after removing the inode from the hash chain. Comment is also updated to better reflect current behavior. This condition is very hard to trigger normally (simultaneous clear_inode() with iget()) so probably only heavy stress testing can reveal any change of behavior. Signed-off-by:

OK, I can see what's happening here. eth0 doesn't detect link-up until after a few seconds, so when the vlan interface is opened immediately after eth0 has been opened, it inherits the link-down state. Subsequently the vlan interface is never properly activated and are thus unable to transmit any packets. dev->state bits are not supposed to be manipulated directly. Something similar is probably needed for the netif_device_present() bit, although I don't know how this is meant to work for a virtual device. Signed-off-by:David S. Miller <davem@davemloft.net>

The following driver provides complete interrupt-in and interrupt-out reports (raw data) to a user program. Until now it uses the HIDIOCGDEVINFO ioctl call, because I don't know better :-(. Perhaps, it will be ok for you - and I will be happy, if you assign 8 minor numbers. I have tested it in several environments and it works very well for me. However, it has a problem with two or more devices at the same hub, if the two or more devices need 1 ms interrupt-in transfers. Unfortunately more than one interrupt-in transfer every ms isn't possible (ehci driver?). This is why the min_interrupt_in_interval and min_interrupt_out_interval are increased to 2 ms (see the corresponding module parameters). This way, I can use two devices simultaneously at the same hub. Signed-off-by:
