2007-04-25[SK_BUFF]: Convert skb->tail to sk_buff_data_tArnaldo Carvalho de Melo
So that it is also an offset from skb->head, reduces its size from 8 to 4 bytes on 64bit architectures, allowing us to combine the 4 bytes hole left by the layer headers conversion, reducing struct sk_buff size to 256 bytes, i.e. 4 64byte cachelines, and since the sk_buff slab cache is SLAB_HWCACHE_ALIGN... :-) Many calculations that previously required that skb->{transport,network, mac}_header be first converted to a pointer now can be done directly, being meaningful as offsets or pointers.

2007-04-25[SK_BUFF]: Introduce skb_transport_header(skb)Arnaldo Carvalho de Melo
For the places where we need a pointer to the transport header, it is still legal to touch skb->h.raw directly if just adding to, subtracting from or setting it to another layer header. Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-04-25[SK_BUFF]: Introduce skb_reset_transport_header(skb)Arnaldo Carvalho de Melo
For the common, open coded 'skb->h.raw = skb->data' operation, so that we can later turn skb->h.raw into a offset, reducing the size of struct sk_buff in 64bit land while possibly keeping it as a pointer on 32bit. This one touches just the most simple cases: skb->h.raw = skb->data; skb->h.raw = {skb_push|[__]skb_pull}() The next ones will handle the slightly more "complex" cases.

2007-03-29[PATCH] bluetooth hid quirks: mightymouse quirkJiri Kosina
I have a bugreport that scrollwheel of bluetooth version of apple mightymouse doesn't work. The USB version of mightymouse works, as there is a quirk for handling scrollwheel in hid/usbhid for it. Now that bluetooth git tree is hooked to generic hid layer, it could easily use the quirks which are already present in generic hid parser, hid-input, etc. Below is a simple patch against bluetooth git tree, which adds quirk handling to current bluetooth hidp code, and sets quirk flags for device 0x05ac/0x030c, which is the bluetooth version of the apple mightymouse.

2007-03-08[PATCH] bluetooth: fix socket locking in hci_sock_dev_event()Jiri Kosina
[Bluetooth] Fix socket locking in hci_sock_dev_event() hci_sock_dev_event() uses bh_lock_sock() to lock the socket lock. This is not deadlock-safe against locking of the same socket lock in l2cap_connect_cfm() from softirq context. In addition to that, hci_sock_dev_event() doesn't seem to be called from softirq context, so it is safe to use lock_sock()/release_sock() instead. The lockdep warning can be triggered on my T42p simply by switching the Bluetooth off by the keyboard button. ================================= [ INFO: inconsistent lock state ] 2.6.21-rc2 #4 --------------------------------- inconsistent {in-softirq-W} -> {softirq-on-W} usage. khubd/156 [HC0[0]:SC0[0]:HE1:SE1] takes: (slock-AF_BLUETOOTH){-+..}, at: [<e0ca5520>] hci_sock_dev_event+0xa8/0xc5 [bluetooth] {in-softirq-W} state was registered at: [<c012d1db>] mark_lock+0x59/0x414 [<e0cef688>] l2cap_connect_cfm+0x4e/0x11f [l2cap] [<c012dfd7>] __lock_acquire+0x3e5/0xb99 [<e0cef688>] l2cap_connect_cfm+0x4e/0x11f [l2cap] [<c012e7f2>] lock_acquire+0x67/0x81 [<e0cef688>] l2cap_connect_cfm+0x4e/0x11f [l2cap] [<c036ee72>] _spin_lock+0x29/0x34 [<e0cef688>] l2cap_connect_cfm+0x4e/0x11f [l2cap] [<e0cef688>] l2cap_connect_cfm+0x4e/0x11f [l2cap] [<e0ca17c3>] hci_send_cmd+0x126/0x14f [bluetooth] [<e0ca4ce4>] hci_event_packet+0x729/0xebd [bluetooth] [<e0ca205b>] hci_rx_task+0x2a/0x20f [bluetooth] [<e0ca209d>] hci_rx_task+0x6c/0x20f [bluetooth] [<c012d7be>] trace_hardirqs_on+0x10d/0x14e [<c011ac85>] tasklet_action+0x3d/0x68 [<c011abba>] __do_softirq+0x41/0x92 [<c011ac32>] do_softirq+0x27/0x3d [<c0105134>] do_IRQ+0x7b/0x8f [<c0103dec>] common_interrupt+0x24/0x34 [<c0103df6>] common_interrupt+0x2e/0x34 [<c0248e65>] acpi_processor_idle+0x1b3/0x34a [<c0248e68>] acpi_processor_idle+0x1b6/0x34a [<c010232b>] cpu_idle+0x39/0x4e [<c04bab0c>] start_kernel+0x372/0x37a [<c04ba42b>] unknown_bootoption+0x0/0x202 [<ffffffff>] 0xffffffff Signed-off-by: Jiri Kosina <jkosina@suse.cz> Acked-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2007-02-14[PATCH] remove many unneeded #includes of sched.hTim Schmielau
After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

2006-10-02[PATCH] const struct tty_operationsJeff Dike
As part of an SMP cleanliness pass over UML, I consted a bunch of structures in order to not have to document their locking. One of these structures was a struct tty_operations. In order to const it in UML without introducing compiler complaints, the declaration of tty_set_operations needs to be changed, and then all of its callers need to be fixed. This patch declares all struct tty_operations in the tree as const. In all cases, they are static and used only as input to tty_set_operations. As an extra check, I ran an i386 allyesconfig build which produced no extra warnings. 53 drivers are affected. I checked the history of a bunch of them, and in most cases, there have been only a handful of maintenance changes in the last six months. serial_core.c was the busiest one that I looked at.
