The recent change to direct inspection of bundle buffer tailroom did not account for the possiblity of unrequested tailroom added by skb_alloc(), thereby allowing a bundle to be created that exceeds the current link MTU. An additional check now ensures that bundling works correctly no matter if the bundle buffer is smaller, larger, or equal to the link MTU. Signed-off-by:

convert: - runqueue_t to 'struct rq' - prio_array_t to 'struct prio_array' - migration_req_t to 'struct migration_req' I was the one who added these but they are both against the kernel coding style and also were used inconsistently at places. So just get rid of them at once, now that we are flushing the scheduler patch-queue anyway. Conversion was mostly scripted, the result was reviewed and all secondary whitespace and style impact (if any) was fixed up by hand. Signed-off-by:

At the moment, powerpc and s390 have their own versions of do_softirq which include local_bh_disable() and __local_bh_enable() calls. They end up calling __do_softirq (in kernel/softirq.c) which also does local_bh_disable/enable. Apparently the two levels of disable/enable trigger a warning from some validation code that Ingo is working on, and he would like to see the outer level removed. But to do that, we have to move the account_system_vtime calls that are currently in the arch do_softirq() implementations for powerpc and s390 into the generic __do_softirq() (this is a no-op for other archs because account_system_vtime is defined to be an empty inline function on all other archs). This patch does that. Signed-off-by:

nv_do_nic_poll() is called from timer softirqs, which has interrupts enabled, but np->lock might also be taken by some other interrupt context. The driver does disable_irq() to get around this problem, so annotate the disable_irq()/enable_irq() calls for lockdep. Has no effect on non-lockdep kernels. Signed-off-by:

Teach sk_lock semantics to the lock validator. In the softirq path the slock has mutex_trylock()+mutex_unlock() semantics, in the process context sock_lock() case it has mutex_lock()/mutex_unlock() semantics. Thus we treat sock_owned_by_user() flagged areas as an exclusion area too, not just those areas covered by a held sk_lock.slock. Effect on non-lockdep kernels: minimal, sk_lock_sock_init() has been turned into an inline function. Signed-off-by:

Teach special (recursive) locking code to the lock validator. Effects on non-lockdep kernels: - the introduction of the following function variants: extern struct block_device *open_partition_by_devnum(dev_t, unsigned); extern int blkdev_put_partition(struct block_device *); static int blkdev_get_whole(struct block_device *bdev, mode_t mode, unsigned flags); which on non-lockdep are the same as open_by_devnum(), blkdev_put() and blkdev_get(). - a subclass parameter to do_open(). [unused on non-lockdep] - a subclass parameter to __blkdev_put(), which is a new internal function for the main blkdev_put*() functions. [parameter unused on non-lockdep kernels, except for two sanity check WARN_ON()s] these functions carry no semantical difference - they only express object dependencies towards the lockdep subsystem.

Teach special (recursive) locking code to the lock validator. Has no effect on non-lockdep kernels. Fix initialize-locks-via-memcpy assumptions. Effects on non-lockdep kernels: the subclass nesting parameter is passed into cache_free_alien() and __cache_free(), and turns one internal kmem_cache_free() call into an open-coded __cache_free() call.

The ops structure has complex locking rules, where not all ops are equal, some are subordinate on others for some complex sound cards.

In usbfs's fs_remove_file() function, the aim is to remove a file or directory from usbfs. This is done by first taking the i_mutex of the parent directory of this file/dir via mutex_lock(&parent->d_inode->i_mutex); and then to call either usbfs_rmdir() for a directory or usbfs_unlink() for a file. Both these functions then take the i_mutex for the to-be-removed object themselves: mutex_lock(&inode->i_mutex); This is a classical parent->child locking order relationship that the VFS uses all over the place; the VFS locking rule is "you need to take the parent first". This patch annotates the usbfs code to make this explicit and thus informs the lockdep code that those two locks indeed have this relationship. The rules for unlink that we already use in the VFS for unlink are to use I_MUTEX_PARENT for the parent directory, and a normal mutex for the file itself; this patch follows that convention. Has no effect on non-lockdep kernels. Signed-off-by:
