2007-10-16block: convert blkdev_issue_flush() to use empty barriersJens Axboe
Then we can get rid of ->issue_flush_fn() and all the driver private implementations of that. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-10-16block: Initial support for data-less (or empty) barrier supportJens Axboe
This implements functionality to pass down or insert a barrier in a queue, without having data attached to it. The ->prepare_flush_fn() infrastructure from data barriers are reused to provide this functionality. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-10-16block: add end_queued_request() and end_dequeued_request() helpersJens Axboe
We can use this helper in the elevator core for BLKPREP_KILL, and it'll also be useful for the empty barrier patch. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

2007-10-15[TCP]: Make snd_cwnd_cnt 32-bitIlpo Järvinen
Very little point of having 32-bit snd_cnwd if this is not 32-bit as well, as a number of snd_cwnd incrementation formulas assume that snd_cwnd_cnt can be at least as large as snd_cwnd. Whether 32-bit is useful was discussed when e0ef57cc56c3c96 was made: http://marc.info/?l=linux-netdev&m=117218144409825&w=2 Signed-off-by: Ilpo Järvinen <ilpo.jarvinen@helsinki.fi> Signed-off-by: David S.

2007-10-15[INET]: Consolidate the xxx_putPavel Emelyanov
These ones use the generic data types too, so move them in one place. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-10-15[INET]: Consolidate the xxx_evictorPavel Emelyanov
The evictors collect some statistics for ipv4 and ipv6, so make it return the number of evicted queues and account them all at once in the caller. The XXX_ADD_STATS_BH() macros are just for this case, but maybe there are places in code, that can make use of them as well. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-10-15[INET]: Consolidate the xxx_frag_destroyPavel Emelyanov
To make in possible we need to know the exact frag queue size for inet_frags->mem management and two callbacks: * to destoy the skb (optional, used in conntracks only) * to free the queue itself (mandatory, but later I plan to move the allocation and the destruction of frag_queues into the common place, so this callback will most likely be optional too). Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-10-15[INET]: Consolidate xxx_the secret_rebuildPavel Emelyanov
This code works with the generic data types as well, so move this into inet_fragment.c This move makes it possible to hide the secret_timer management and the secret_rebuild routine completely in the inet_fragment.c Introduce the ->hashfn() callback in inet_frags() to get the hashfun for a given inet_frag_queue() object. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-10-15[INET]: Consolidate the xxx_frag_killPavel Emelyanov
Since now all the xxx_frag_kill functions now work with the generic inet_frag_queue data type, this can be moved into a common place. The xxx_unlink() code is moved as well. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-10-15[INET]: Collect common frag sysctl variables togetherPavel Emelyanov
Some sysctl variables are used to tune the frag queues management and it will be useful to work with them in a common way in the future, so move them into one structure, moreover they are the same for all the frag management codes. I don't place them in the existing inet_frags object, introduced in the previous patch for two reasons: 1. to keep them in the __read_mostly section; 2. not to export the whole inet_frags objects outside. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-10-15[INET]: Collect frag queues management objects togetherPavel Emelyanov
There are some objects that are common in all the places which are used to keep track of frag queues, they are: * hash table * LRU list * rw lock * rnd number for hash function * the number of queues * the amount of memory occupied by queues * secret timer Move all this stuff into one structure (struct inet_frags) to make it possible use them uniformly in the future. Like with the previous patch this mostly consists of hunks like - write_lock(&ipfrag_lock); + write_lock(&ip4_frags.lock); To address the issue with exporting the number of queues and the amount of memory occupied by queues outside the .c file they are declared in, I introduce a couple of helpers. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-10-15[INET]: Move common fields from frag_queues in one place.Pavel Emelyanov
Introduce the struct inet_frag_queue in include/net/inet_frag.h file and place there all the common fields from three structs: * struct ipq in ipv4/ip_fragment.c * struct nf_ct_frag6_queue in nf_conntrack_reasm.c * struct frag_queue in ipv6/reassembly.c After this, replace these fields on appropriate structures with this structure instance and fix the users to use correct names i.e. hunks like - atomic_dec(&fq->refcnt); + atomic_dec(&fq->q.refcnt); (these occupy most of the patch) Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S.

2007-10-15[NETFILTER]: Replace sk_buff ** with sk_buff *Herbert Xu

2007-10-15[IPVS]: Replace local version of skb_make_writableHerbert Xu

2007-10-15[NETFILTER]: Do not copy skb in skb_make_writableHerbert Xu
Now that all callers of netfilter can guarantee that the skb is not shared, we no longer have to copy the skb in skb_make_writable. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-10-15[IPV4]: Change ip_defrag to return an integerHerbert Xu
Now that ip_frag always returns the packet given to it on input, we can change it to return an integer indicating error instead. This patch does that and updates all its callers accordingly. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-10-15[SKBUFF]: Add skb_morphHerbert Xu
This patch creates a new function skb_morph that's just like skb_clone except that it lets user provide the spare skb that will be overwritten by the one that's to be cloned. This will be used by IP fragment reassembly so that we get back the same skb that went in last (rather than the head skb that we get now which requires us to carry around double pointers all over the place).

2007-10-15Use dcr_host_t.base in dcr_unmap()Michael Ellerman
With the base stored in dcr_host_t, there's no need for callers to pass the dcr_n into dcr_unmap(). In fact this removes the possibility of them passing the incorrect value, which would then be iounmap()'ed.

2007-10-15Add dcr_host_t.base in dcr_read()/dcr_write()Michael Ellerman
Now that all users of dcr_read()/dcr_write() add the dcr_host_t.base, we can save them the trouble and do it in dcr_read()/dcr_write(). As some background to why we just went through all this jiggery-pokery, benh sayeth: Initially the goal of the dcr_read/dcr_write routines was to operate like mfdcr/mtdcr which take absolute DCR numbers. The reason is that on 4xx hardware, indirect DCR access is a pain (goes through a table of instructions) and it's useful to have the compiler resolve an absolute DCR inline. We decided that wasn't worth the API bastardisation since most places where absolute DCR values are used are low level 4xx-only code which may as well continue using mfdcr/mtdcr, while the new API is designed for device "instances" that can exist on 4xx and Axon type platforms and may be located at variable DCR offsets.

2007-10-15[ARM] pxa: Avoid pxa_gpio_mode() in gpio_direction_{in,out}put()Russell King
pxa_gpio_mode() is a universal call that fiddles with the GAFR (gpio alternate function register.) GAFR does not exist on PXA3 CPUs, but instead the alternate functions are controlled via the MFP support code. Platforms are expected to configure the MFP according to their needs in their platform support code rather than drivers. We extend this idea to the GAFR, and make the gpio_direction_*() functions purely operate on the GPIO level. This means platform support code is entirely responsible for configuring the GPIOs alternate functions on all PXA CPU types. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2007-10-15sched: guest CPU accounting: maintain stats in account_system_time()Laurent Vivier
modify account_system_time() to add cputime to cpustat->guest if we are running a VCPU. We add this cputime to cpustat->user instead of cpustat->system because this part of KVM code is in fact user code although it is executed in the kernel. We duplicate VCPU time between guest and user to allow an unmodified "top(1)" to display correct value. A modified "top(1)" is able to display good cpu user time and cpu guest time by subtracting cpu guest time from cpu user time. Update "gtime" in task_struct accordingly.
