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[NET_SCHED]: sch_cbq: fix watchdog scheduled too latePatrick McHardy
q->now is increased during dequeue and doesn't contain the current time afterwards, resulting in a too large timeout value for the qdisc watchdog. Use "now" instead, which still contains the current time. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-04-25[NET_SCHED]: sch_cbq: use hrtimer for delay_timerPatrick McHardy
Switch delay_timer to hrtimer. The class penalty parameter is changed to use psched ticks as units. Since iproute never supported using this and the only existing user (libnl) incorrectly assumes psched ticks as units anyway, this shouldn't break anything.

2007-04-25[NET_SCHED]: sch_cbq: fix cbq_undelay_prio for non-active prioritesPatrick McHardy
cbq_undelay_prio is supposed to return a time delta, but returns the current time for non-active priorities, causing cbq_undelay to mark the priority as active and schedule a timer for twice the current time.

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).

2006-12-08[NET_SCHED] sch_cbq: deactivating when grafting, purging etc.Jarek Poplawski
- deactivating of active classes when q.qlen drops to zero (cbq_drop) - a redundant instruction removed from cbq_deactivate_class PS: probably htb_deactivate in htb_delete and cbq_deactivate_class in cbq_delete are also redundant now.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
