2005-11-01[PATCH] blk: fix dangling pointer access in __elv_add_requestTejun Heo
cfq's add_req_fn callback may invoke q->request_fn directly and depending on low-level driver used and timing, a queued request may be finished & deallocated before add_req_fn callback returns. So, __elv_add_request must not access rq after it's passed to add_req_fn callback. This patch moves rq_mergeable test above add_req_fn(). This may result in q->last_merge pointing to REQ_NOMERGE request if add_req_fn callback sets it but as RQ_NOMERGE is checked again when blk layer actually tries to merge requests, this does not cause any problem.

Jeff Garzik <jgarzik@pobox.com> points out that this was wrong: we need to disable local interrupts while holding KM_IRQ0 due to IRQ sharing.

2005-10-31[PATCH] noop-iosched: avoid corrupted request mergingJens Axboe
Tejun Heo notes: "I'm currently debugging this. The problem is that we are using the generic dispatch queue directly in the noop sched and merging is NOT allowed on dispatch queues but generic handling of last_merge tries to merge requests. I'm still trying to verify this, so I'll be back with results soon." In the meantime, disable merging for noop by setting REQ_NOMERGE in elevator_noop_add_request(). Eventually, we should add a noop_list and do the dispatching like in the other io schedulers. Merging is still beneficial for noop (and it has always done it).

2005-10-30[libata] locking rewrite (== fix)Jeff Garzik
A lot of power packed into a little patch. This change eliminates the sharing between our controller-wide spinlock and the SCSI core's Scsi_Host lock. As the locking in libata was already highly compartmentalized, always referencing our own lock, and never scsi_host::host_lock. As a side effect, this change eliminates a deadlock from calling scsi_finish_command() while inside our spinlock.
2005-10-30[libata] ata_tf_to_host cleanupsJeff Garzik
Integrate ata_exec() and ata_tf_to_host() into their only caller, ata_bus_edd(). Rename ata_tf_to_host_nolock() to ata_tf_to_host(). This makes locking a bit easier to review, and may help pave the way for future changes.

2005-10-30[PATCH] fix missing includesTim Schmielau
I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

This patch adds support for shared HPET interrupts. The driver previously acknowledged interrupts for both edge and level interrupts, but didn't actually allow a shared interrupt in the latter case.

2005-10-30[PATCH] HPET: make frequency calculations 32 bit safeClemens Ladisch
On 32-bit architectures, the multiplication in the argument for hpet_time_div() often overflows. In the typical case of a 14.32 MHz timer, this happens when the desired frequency exceeds 61 Hz. To avoid this multiplication, we can precompute and store the hardware timer frequency, instead of the period, in the device structure, which leaves us with a simple division when computing the number of timer ticks. As a side effect, this also removes a theoretical bug where the timer interpolator's frequency would be computed as a 32-bit value even if the HPET frequency is greater than 2^32 Hz (the HPET spec allows up to 10 GHz).
