Linux-2.6.12-rc2 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!

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.

ide: preserve Host Protected Area by default (v2) From the perspective of most users of recent systems, disabling Host Protected Area (HPA) can break vendor RAID formats, GPT partitions and risks corrupting firmware or overwriting vendor system recovery tools. Unfortunately the original (kernels < 2.6.30) behavior (unconditionally disabling HPA and using full disk capacity) was introduced at the time when the main use of HPA was to make the drive look small enough for the BIOS to allow the system to boot with large capacity drives. Thus to allow the maximum compatibility with the existing setups (using HPA and partitioned with HPA disabled) we automically disable HPA if any partitions overlapping HPA are detected. Additionally HPA can also be disabled using the "nohpa" module parameter (i.e. "ide_core.nohpa=0.0" to disable HPA on /dev/hda). v2: Fix ->resume HPA support.

ide-disk: Fix request requeuing Simon Kirby reported that on his RAID setup with idedisk underneath the box OOMs after a couple of days of runtime. Running with CONFIG_DEBUG_KMEMLEAK pointed to idedisk_prep_fn() which unconditionally allocates an ide_cmd struct. However, ide_requeue_and_plug() can be called more than once per request, either from the request issue or the IRQ handler path and do blk_peek_request() ends up in idedisk_prep_fn() repeatedly, allocating a struct ide_cmd everytime and "forgetting" the previous pointer. Make sure the code reuses the old allocated chunk.

ide-disk: fix flush requests (take 2) commit 813a0eb233ee67d7166241a8b389b6a76f2247f9 Author: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com> Date: Fri Jan 25 22:17:10 2008 +0100 ide: switch idedisk_prepare_flush() to use REQ_TYPE_ATA_TASKFILE requests ... broke flush requests. Allocating IDE command structure on the stack for flush requests is not a very brilliant idea: - idedisk_prepare_flush() only prepares the request and it doesn't wait for it to be completed - there are can be multiple flush requests queued in the queue Fix the problem (per hints from James Bottomley) by: - dynamically allocating ide_task_t instance using kmalloc(..., GFP_ATOMIC) - adding new taskfile flag (IDE_TFLAG_DYN) - calling kfree() in ide_end_drive_command() if IDE_TFLAG_DYN is set (while at it rename 'args' to 'task' and fix whitespace damage) [ This will be fixed properly before 2.6.25 but this bug is rather critical and the proper solution requires some more work + testing. ] Thanks to Sebastian Siewior and Christoph Hellwig for reporting the problem and testing patches (extra thanks to Sebastian for bisecting it to the guilty commmit).

ide: fix memory leak when flush command is issued I'm using ide on 2.6.30.1 with xfs filesystem. I noticed a kernel memory leak after writing lots of data, the kmalloc-96 slab cache keeps growing. It seems the struct ide_cmd kmalloced by idedisk_prepare_flush is never kfreed. Commit a09485df9cda49fbde2766c86eb18a9cae585162 ("ide: move request type specific code from ide_end_drive_cmd() to callers (v3)") and f505d49ffd25ed062e76ffd17568d3937fcd338c ("ide: fix barriers support") cause this regression, cmd->rq must now be set for ide_complete_cmd to honor the IDE_TFLAG_DYN flag.

ide: replace IDE_TFLAG_* flags by IDE_VALID_* Replace IDE_TFLAG_{IN|OUT}_* flags meaning to the taskfile register validity on input/output by the IDE_VALID_* flags and introduce 4 symmetric 8-bit register validity indicator subfields, 'valid.{input/output}.{tf|hob}', into the 'struct ide_cmd' instead of using the 'tf_flags' field for that purpose (this field can then be turned from 32-bit into 8-bit one).

Then convert all existing drive->id users accordingly (using 'u16 *id' when possible). This is an intermediate step to make ide 'struct hd_driveid'-free.

Linux-2.6.12-rc2 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.

[BLOCK] update IDE to use new blk_ordered for barriers Update IDE to use new blk_ordered. This change makes the following behavior changes. * Partial completion of the barrier request is handled as failure of the whole ordered sequence. No more partial completion for barrier requests. * Any failure of pre or post flush request results in failure of the whole ordered sequence. So, successfully completed ordered sequence guarantees that all requests prior to the barrier made to physical medium and, then, the while barrier request made to the physical medium.

ide: add generic ATA/ATAPI disk driver * Add struct ide_disk_ops containing protocol specific methods. * Add 'struct ide_disk_ops *' to ide_drive_t. * Convert ide-{disk,floppy} drivers to use struct ide_disk_ops. * Merge ide-{disk,floppy} drivers into generic ide-gd driver. While at it: - ide_disk_init_capacity() -> ide_disk_get_capacity() Acked-by: Borislav Petkov <petkovbb@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

block,ide: simplify bdops->set_capacity() to ->unlock_native_capacity() bdops->set_capacity() is unnecessarily generic. All that's required is a simple one way notification to lower level driver telling it to try to unlock native capacity. There's no reason to pass in target capacity or return the new capacity. The former is always the inherent native capacity and the latter can be handled via the usual device resize / revalidation path. In fact, the current API is always used that way. Replace ->set_capacity() with ->unlock_native_capacity() which take only @disk and doesn't return anything. IDE which is the only current user of the API is converted accordingly.
