2008-08-29remove blk_register_filter and blk_unregister_filter in gendiskFUJITA Tomonori
This patch remove blk_register_filter and blk_unregister_filter in gendisk, and adds them to sd.c, sr.c. and ide-cd.c The commit abf5439370491dd6fbb4fe1a7939680d2a9bc9d4 moved cmdfilter from gendisk to request_queue. It turned out that in some subsystems multiple gendisks share a single request_queue. So we get: Using physmap partition information Creating 3 MTD partitions on "physmap-flash": 0x00000000-0x01c00000 : "User FS" 0x01c00000-0x01c40000 : "booter" kobject (8511c410): tried to init an initialized object, something is seriously wrong.

This patch add the command filter support to only sd and sr though it might be useful for other SG_IO users (such as cciss).

2008-08-05ide-cd: fix endianity for the error message in cdrom_read_capacityPetr Tesarik
Aesthetic regards aside, commit e8e7b9eb11c34ee18bde8b7011af41938d1ad667 still leaves a bug in the error message, because it uses the unconverted big-endian value for printk. Fix this by using a local variable in machine byte order. The result is correct, more readable, and also produces slightly shorter code on i386.

Fix it by calling ide_device_get() before kref_get() and ide_device_put() after kref_put() in all affected device drivers. v2: Brown paper bag time. In v1 cd->drive was referenced after dropping last reference on cd object (which could result in OOPS in ide_device_put() as reported/debugged by Mariusz Kozlowski).

2008-04-26ide: add struct ide_dma_ops (take 3)Bartlomiej Zolnierkiewicz
Add struct ide_dma_ops and convert core code + drivers to use it. While at it: * Drop "ide_" prefix from ->ide_dma_end and ->ide_dma_test_irq methods. * Drop "ide_" "infixes" from DMA methods. * au1xxx-ide.c: - use auide_dma_{test_irq,end}() directly in auide_dma_timeout() * pdc202xx_old.c: - drop "old_" "infixes" from DMA methods * siimage.c: - add siimage_dma_test_irq() helper - print SATA warning in siimage_init_one() * Remove no longer needed ->init_hwif implementations. v2: * Changes based on review from Sergei: - s/siimage_ide_dma_test_irq/siimage_dma_test_irq/ - s/drive->hwif/hwif/ in idefloppy_pc_intr(). - fix patch description w.r.t. au1xxx-ide changes - fix au1xxx-ide build - fix naming for cmd64*_dma_ops - drop "ide_" and "old_" infixes - s/hpt3xxx_dma_ops/hpt37x_dma_ops/ - s/hpt370x_dma_ops/hpt370_dma_ops/ - use correct DMA ops for HPT302/N, HPT371/N and HPT374 - s/it821x_smart_dma_ops/it821x_pass_through_dma_ops/ v3: * Two bugs slipped in v2 (noticed by Sergei): - use correct DMA ops for HPT374 (for real this time) - handle HPT370/HPT370A properly Acked-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2008-04-26ide-cd: remove the internal 64k bufferBorislav Petkov
This removes the internal ide-cd buffer and falls back to read-ahead block layer capabilities. Thorough testing (cd burning, dvd read, raw read) gives with the bufferless mode marginally better performance in addition to simplified code. bufferless: dd: reading `/dev/hdc': Input/output error 6238+0 records in 6238+0 records out 204406784 bytes (204 MB) copied, 259.891 s, 787 kB/s real 4m21.598s user 0m0.014s sys 0m0.744s with the old buffer (2.6.25-rc1): dd: reading `/dev/hdc': Input/output error 6238+0 records in 6238+0 records out 204406784 bytes (204 MB) copied, 262.893 s, 778 kB/s real 4m22.938s user 0m0.009s sys 0m0.771s Signed-off-by: Borislav Petkov <petkovbb@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2008-04-18ide: remove IDE_*_REG macrosBartlomiej Zolnierkiewicz
* Add IDE_{ALTSTATUS,IREASON,BCOUNTL,BCOUNTH}_OFFSET defines. * Remove IDE_*_REG macros - this results in more readable and slightly smaller code. There should be no functional changes caused by this patch.
