2010-08-07block: don't allocate a payload for discard requestChristoph Hellwig4-45/+74
Allocating a fixed payload for discard requests always was a horrible hack, and it's not coming to byte us when adding support for discard in DM/MD. So change the code to leave the allocation of a payload to the lowlevel driver. Unfortunately that means we'll need another hack, which allows us to update the various block layer length fields indicating that we have a payload. Instead of hiding this in sd.c, which we already partially do for UNMAP support add a documented helper in the core block layer for it.

2010-08-07virtio_blk: add default case to cmd type switchJens Axboe1-0/+2
On compilation, gcc correctly detects that we do not handle all types: In function ‘blk_done’: warning: enumeration value ‘REQ_TYPE_FS’ not handled in switch warning: enumeration value ‘REQ_TYPE_SENSE’ not handled in switch warning: enumeration value ‘REQ_TYPE_PM_SUSPEND’ not handled in switch warning: enumeration value ‘REQ_TYPE_PM_RESUME’ not handled in switch warning: enumeration value ‘REQ_TYPE_PM_SHUTDOWN’ not handled in switch warning: enumeration value ‘REQ_TYPE_LINUX_BLOCK’ not handled in switch warning: enumeration value ‘REQ_TYPE_ATA_TASKFILE’ not handled in switch warning: enumeration value ‘REQ_TYPE_ATA_PC’ not handled in switch which is a bit pointless since this is at the end of the request processessing. Add a default case that just breaks out. Signed-off-by: Jens Axboe <jaxboe@fusionio.com>
2010-08-07block: unify flags for struct bio and struct requestChristoph Hellwig47-289/+242
Remove the current bio flags and reuse the request flags for the bio, too. This allows to more easily trace the type of I/O from the filesystem down to the block driver. There were two flags in the bio that were missing in the requests: BIO_RW_UNPLUG and BIO_RW_AHEAD. Also I've renamed two request flags that had a superflous RW in them. Note that the flags are in bio.h despite having the REQ_ name - as blkdev.h includes bio.h that is the only way to go for now.

2010-08-07block: kill ISA_DMA_THRESHOLD usageFUJITA Tomonori1-1/+1
block uses ISA_DMA_THRESHOLD for BLK_BOUNCE_ISA. Only SCSI uses ISA_DMA_THRESHOLD for ancient drivers with non-zero unchecked_isa_dma. Nowadays drivers (and subsystems) use dma_mask properly instead of ISA_DMA_THRESHOLD. Documentation/scsi/scsi_mid_low_api.txt says: unchecked_isa_dma - 1=>only use bottom 16 MB of ram (ISA DMA addressing restriction), 0=>can use full 32 bit (or better) DMA address space So block simply uses DMA_BIT_MASK(24) for BLK_BOUNCE_ISA for SCSI.

We can safely remove ISA_DMA_THRESHOLD usage in aha1542. aha1542 uses ISA_DMA_THRESHOLD to see if: - the buffers in scatter/list are below 16MB. - scsi_host is below 16MB. Both checkings were added in the ancient times but aren't necessary nowadays since we properly bounce the buffers and allocate scsi_host below 16MB with non-zero unchecked_isa_dma.

2010-08-07block: BARRIER request should imply SYNCChristoph Hellwig2-3/+3
A barrier request should by defintion have priority in get_request and let the queue be unplugged immediately as it's blocking all forward progress due to the queue draining. Most filesystems already get this implicitly by the way how submit_bh treats the buffer_ordered flag, and gfs2 sets it explicitly. But btrfs and XFS are still forgetting to set the flag, as is blkdev_issue_flush and some places in DM/MD. For XFS on metadata heavy workloads this gives a consistent speedup in the 2-3% range.

2010-08-07block: add sysfs knob for turning off disk entropy contributionsJens Axboe3-2/+34
There are two reasons for doing this: - On SSD disks, the completion times aren't as random as they are for rotational drives. So it's questionable whether they should contribute to the random pool in the first place. - Calling add_disk_randomness() has a lot of overhead. This adds /sys/block/<dev>/queue/add_random that will allow you to switch off on a per-device basis. The default setting is on, so there should be no functional changes from this patch.

2010-08-07cciss: add performant mode support for Stars/SiriusMike Miller4-63/+353
Add a mode of controller operation called Performant Mode. Even though cciss has been deprecated in favor of hpsa there are new controllers due out next year that HP must support in older vendor distros. Vendors require all fixes/features be upstream. These new controllers support only 16 commands in simple mode but support up to 1024 in performant mode. This requires us to add this support at this late date. The performant mode transport minimizes host PCI accesses by performinf many completions per read. PCI writes are posted so the host can write then immediately get off the bus not waiting for the writwe to complete to the target. In the context of performant mode the host read out to a controller pulls all posted writes into host memory ensuring the reply queue is coherent.

2010-07-30mm: fix ia64 crash when gcore reads gate areaHugh Dickins1-3/+13
Debian's ia64 autobuilders have been seeing kernel freeze or reboot when running the gdb testsuite (Debian bug 588574): dannf bisected to 2.6.32 62eede62dafb4a6633eae7ffbeb34c60dba5e7b1 "mm: ZERO_PAGE without PTE_SPECIAL"; and reproduced it with gdb's gcore on a simple target. I'd missed updating the gate_vma handling in __get_user_pages(): that happens to use vm_normal_page() (nowadays failing on the zero page), yet reported success even when it failed to get a page - boom when access_process_vm() tried to copy that to its intermediate buffer. Fix this, resisting cleanups: in particular, leave it for now reporting success when not asked to get any pages - very probably safe to change, but let's not risk it without testing exposure. Why did ia64 crash with 16kB pages, but succeed with 64kB pages? Because setup_gate() pads each 64kB of its gate area with zero pages.
