Add ACPI bus_type for Linux driver model. 1. .shutdown method is added into acpi_driver.ops needed by bus_type operations. 2. remove useless parameter 'int state' in .resume method. 3. change parameter 'int state' to 'pm_message_t state' in .suspend method. Note: The new .uevent method mark ACPI drivers by PNPID instead of by name. Udev script needs to look for "HWID=" or "COMPTID=" to load ACPI drivers as a result.

Currently in SCTP, we maintain a local address list by rebuilding the whole list from the device list whenever we get a address add/delete event. This patch fixes it by only adding/deleting the address for which we receive the event. Also removed the sctp_local_addr_lock() which is no longer needed as we now use list_for_each_safe() to traverse this list. This fixes the bugs in sctp_copy_laddrs_xxx() routines where we do copy_to_user() while holding this lock. Signed-off-by: NSridhar Samudrala <sri@us.ibm.com> Signed-off-by: NDavid S.

In a recent patch we introduced invalid return codes which will result in the opposite of what is intended (i.e. send more packets in face of peculiar network conditions).

If we come to node we'd already marked as seen and it's not a part of path (i.e. we don't have a loop right there), we already know that it isn't a part of any loop, so we don't need to revisit it. That speeds the things up if some chain is refered to from several places and kills O(exp(table size)) worst-case behaviour (without sleeping, at that, so if you manage to self-LART that way, you are SOL for a long time)...

Fix file and directory removal in debugfs. Add inotify support for file removal. The following scenario : create dir a create dir a/b cd a/b (some process goes in cwd a/b) rmdir a/b rmdir a fails due to the fact that "a" appears to be non empty. It is because the "b" dentry is not deleted from "a" and still in use. The same problem happens if "b" is a file. d_delete is nice enough to know when it needs to unhash and free the dentry if nothing else is using it or, if someone is using it, to remove it from the hash queues and wait for it to be deleted when it has no users. The nice side-effect of this fix is that it calls the file removal notification. Signed-off-by: NMathieu Desnoyers <mathieu.desnoyers@polymtl.ca> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

Correct dentry count to handle creation errors. This patch puts a dput at the file creation instead of the file removal : lookup_one_len already returns a dentry with reference count of 1. Then, the dget() in simple_mknod increments it when the dentry is associated with a file. In a scenario where simple_create or simple_mkdir returns an error, this would lead to an unwanted increment of the reference counter, therefore making file removal impossible.

optimization The gcc manual says: |`-fdelete-null-pointer-checks' | Use global dataflow analysis to identify and eliminate useless | checks for null pointers. The compiler assumes that dereferencing | a null pointer would have halted the program. If a pointer is | checked after it has already been dereferenced, it cannot be null. | Enabled at levels `-O2', `-O3', `-Os'. Now the problem can be seen with this test case: #include <linux/prefetch.h> extern void bar(char *x); void foo(char *x) { prefetch(x); if (x) bar(x); } Because the constraint to the inline asm used in the prefetch() macro is a memory operand, gcc assumes that the asm code does dereference the pointer and the delete-null-pointer-checks optimization kicks in. Inspection of generated assembly for the above example shows that bar() is indeed called unconditionally without any test on the value of x. Of course in the prefetch case there is no real dereference and it cannot be assumed that a null pointer would have been caught at that point. This causes kernel oopses with constructs like hlist_for_each_entry() where the list's 'next' content is prefetched before the pointer is tested against NULL, and only when gcc feels like applying this optimization which doesn't happen all the time with more complex code. It appears that the way to prevent delete-null-pointer-checks optimization to occur in this case is to make prefetch() into a static inline function instead of a macro. At least this is what is done on x86_64 where a similar inline asm memory operand is used (I presume they would have seen the same problem if it didn't work) and resulting code for the above example confirms that. An alternative would consist of replacing the memory operand by a register operand containing the pointer, and use the addressing mode explicitly in the asm template. But that would be less optimal than an offsettable memory reference. Signed-off-by: NNicolas Pitre <nico@cam.org> Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>
