* [BLOCK] elevator: elv_latter/former_request updateTejun Heo2005-11-12
| | | | | | | | | | | | With generic dispatch queue update, implicit former/latter request handling using rq->queuelist.prev/next doesn't work as expected anymore. Also, the only iosched dependent on this feature was noop-iosched and it has been reimplemented to have its own latter/former methods. This patch removes implicit former/latter handling.

* [BLOCK] noop-iosched: reimplementation of request dispatchingTejun Heo2005-11-12
| | | | | | | | | | | | The original implementation directly used dispatch queue. As new generic dispatch queue imposes stricter rules over ioscheds and dispatch queue usage, this direct use becomes somewhat problematic. This patch reimplements noop-iosched such that it complies to generic iosched model better. Request merging with q->last_merge and rq->queuelist.prev/next work again now.

* [BLOCK] cfq-iosched: fix slice_left calculationTejun Heo2005-11-12
| | | | | | | | | | When cfq slice expires, remainder of slice is calculated and stored in cfqq->slice_left. Current code calculates the opposite of remainder - how many jiffies the cfqq has used past slice end. This patch fixes the bug.

* [BLOCK] fix string handling in elv_iosched_storeTejun Heo2005-11-12
| | | | | | | | | elv_iosched_store doesn't terminate string passed from userspace if it's too long. Also, if the written length is zero (probably not possible), it accesses elevator_name[-1]. This patch fixes both bugs. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jens Axboe <axboe@suse.de>
* [BLOCK] Implement elv_drain_elevator for improved switch error detectionTejun Heo2005-11-12
| | | | | | | | | | | | This patch adds request_queue->nr_sorted which keeps the number of requests in the iosched and implement elv_drain_elevator which performs forced dispatching. elv_drain_elevator checks whether iosched actually dispatches all requests it has and prints error message if it doesn't. As buggy forced dispatching can result in wrong barrier operations, I think this extra check is worthwhile. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jens Axboe <axboe@suse.de>

* [BLOCK] elevator init fixesZachary Amsden2005-11-12
| | | | | | | | | | | | | | | | | | | | | | | | I got a panic in the elevator code, backtrace : Unable to handle kernel NULL pointer dereference at virtual address 00000060 .. EIP is at elevator_put+0x0/0x30 (null elevator_type passed) .. elevator_init+0x38 blk_init_queu_node+0xc9 floppy_init+0xdb do_initcalls+0x23 init+0x10a init+0x0 Clearly if the kmalloc here fails, e->elevator_type is not yet set; this appears to be the correct fix, but I think I probably hit the second case due to a race condition. Someone more familiar with the elevator code should look at this more closely until I can determine if I can reproduce.

| * [SCTP]: Fix ia64 NaT consumption fault with sctp_sideffect commands.Vladislav Yasevich2005-11-11
| | | | | | | | | | | | | | | | | | | | | | | | | | On ia64, it is possible to get NaT Consumption Fault and a kernel panic when initializing sctp sideeffect commands arguments. The union sctp_arg_t contains different sized elements and when loading a smaller sized element (32 or 16 bits), it is possible for a speculative load to fail and result in a NaT bit set which causes a kernel crash. The easy way to get around it is to load the largerst member of the union.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | It is possible to get to sctp_v4_get_saddr() without a valid association. This happens when processing OOTB packets and the cached route entry is no longer valid. However, when responding to OOTB packets we already properly set the source address based on the information in the OOTB packet. So, if we we get to sctp_v4_get_saddr() without an association we can simply return.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix default VGA console on SN platforms. Since SN firmware does not pass enough ACPI information to identify VGA cards and the associated legacy IO/MEM addresses, we rely on the EFI PCDP table. Since the linux pcdp driver is optional (and overridden if console= directives are used) SN duplicates a portion of the pcdp scan code to identify if there is a usable console VGA adapter. Additionally, dup necessary pcdp related structs to avoid dragging drivers/pcdp.h into a more public location. Signed-off-by: Mark Maule <maule@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
