Reduce the "rain forest" of pointers a bit. - Use the channel info from the drive instead of from hwgroup where possible. Since we have now a direct association between a channel and irq, we can fix the handler for unexpected interrupts to don't have to iterate over multiple possibilities. - Finally it was just possible to remove the circular list of channels associated with a hwif. The hwif member of struct hwgroup_s as well as next member if struct ata_channel are gone. - Unify ide_build_sglist() and raw_build_sglist() in to one function. Use the queue associated with a request in the case of a CMD request there instead of referencing the device minor number. This will be pushed even further later.

Some of the following is a bit of sensitive... but anyway it has to be done. - Scarp "portability" macros ide_request_irq() and ide_free_irq(). What a great of a surprise in the face of a kernel nowadays ported to nearly any major CPU out there, but apparently no platform needs something special here. All of them are just using the normal request_irq() and free_irq(). If some unusual platform (read obsolete door blocker) I have overlooked intentionally needs something special - please just hack the platform specific request_irq() and free_irq()- they are *far off* from being performance relevant. (Hint: You could use cooked default irq values to detect there whatever the caller was the ATA driver to decide what to do about it.) - Kill ide_check_region() ide_request_region() and ide_release_region() altogether. Add comments explaining the code there. Same arguments as above apply. Additionally we want to be able at some time to do for example mmapped PCI address space access on IA32 instead of port IO. - Rewrite the initialization code to don't use check_region at all. Add some comments there, which explain what's actually happening. - Fix creeping in of a c99 construct. - Make the main interrupt handler take a channel as data instead of the hwgroup. This is the entity an interrupt is physically associated with. PCI interrupt sharing is handled in a generically anyway. Analogously the main data entity of a device request queue (q->queuedata) is the device and not the hwgroup. However right now we are only able to push it down to the channel level. The intention is to advance the choose_drive() function to just check for equal interrupt values for serialization of request and thus to get rid of the hwgroup altogether.

- Streamline the usage of sector_t over the strategy routines in question a bit. Streamline the do_request code in ide-disk.c. - Improve the readability of start_request in ide.c. - Remove obsolete/nowhere used stuff from hdreg.h. - Splitup special_t into classical flag field. - Use only a single field to determine the capacity of a drive. Make this field and the code paths it follows as far as possible use the sector_t instead of a hard coded integer types. This increases the chances that at some distant point in time we will indeed be able to use 64 bit wide sector_t entities. (Disks are getting huge those times now...)

- Initialise the per-request_queue readahead parameter properly, rather than the dopey "if it's zero you get the deafult" approach. - Permit zero-length readahead. - 80-columnify mm/readahead.c

Get rid of traces of the old-style ALL_MOBJS variable. This also fixes the following issue, which could cause a warning with certain configs: Makefiles (legally) do: obj-$(CONFIG_SND_AD1848) += snd-pcm.o snd-timer.o snd.o obj-$(CONFIG_SND_CS4231) += snd-pcm.o snd-timer.o snd.o snd-rawmidi.o so when the first option is set to y, the second to m, we have e.g. snd-pcm.o on both $(obj-y) and $(obj-m). We correctly don't build the modular version in this case. However, if snd-pcm.o was a multi-part object, we did automatically generate a link rule for both the modular and the built-in version, which caused a warning - that's now fixed.

- switch md_error() to struct block_device * - just cleaning up after ->bi_dev switch.
-
Alexander Viro authored
- bdevname() switched to struct block_device *. Old variant (taking kdev_t) renamed to __bdevname() (very few callers remain). This allow to drop ->b_dev conveniently - it's duplicated by ->b_bdev and most of remaining users were bdevname(bh->b_dev) in various places.
-
Alexander Viro authored
- *NOW* all places that (re)assign ->bi_dev have relevant struct block_device *. ->bi_bdev (struct block_device * equivalent of ->bi_dev) introduced, ->bi_dev removed, users updated.

- this one is interesting and will play in the next series as well; affected place is fs/block_dev.c::do_open(). We check if bdev is a partition (same way it is done in generic_make_request()) and if it is - open entire disk and put pointer to its bdev into a new field bdev->bd_contains. Otherwise (non-partition) we set bdev->bd_contains to bdev. Corresponding cleanup done in blkdev_put() (and failure path in do_open()) - when the last opener goes away we close bdev->bd_contains if bdev is a partition (i.e. not equal to its ->bd_contains) and set it to NULL. Immediate effect is that we can get from bdev of partition to bdev of disk when submitting a bio, but it also opens a way to handle partition-parsing in a sane way. That will be done in the next series.

This patch makes detection of a FAT filesystem more exact by checking the first FAT entry.
-
Hirofumi Ogawa authored
Currently fatfs disregards most wrong cluster chains, and only continues processing. This fixes it. If a wrong cluster chain is detected, change filesystem to the read only, and return the error code.

- Revoke the TCQ stuff. Well having it for some time showed just nicely what has to be done before it can be included cleanly. But it's just not ready yet. For more explanations please simply track the usage of the special field of struct request - *both* in the generic request handling code and in overall driver code.

Forward port changes from 2.4.19-pre, originally by Keith Owens. This driver used to build a module target called "aic7xxx_mod.o" and introduced the MOD_TARGET variable to rename it to "aic7xxx.o" at modules_install time. Now, we just build "aic7xxx.o" directly, which becomes possible after renaming aic7xxx.c to aic7xxx_core.c, as done in 2.4.19-pre.
