* [SCSI] export command allocation and freeing functions independently of the hostJames Bottomley2008-04-07

* [SCSI] scsi: add wrapper functions for sg buffer copy helper functionsFUJITA Tomonori2008-04-07
| | | | | | | | | | | | | | | | LLDs need to copies data between the SG table in struct scsi_cmnd and liner buffer. So they use the helper functions like sg_copy_from_buffer(scsi_sglist(sc), scsi_sg_count(sc), buf, buflen) sg_copy_to_buffer(scsi_sglist(sc), scsi_sg_count(sc), buf, buflen) This patch just adds wrapper functions: scsi_sg_copy_from_buffer(sc, buf, buflen) scsi_sg_copy_to_buffer(sc, buf, buflen) Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
* [SCSI] block: add sg buffer copy helper functionsFUJITA Tomonori2008-04-07
| | | | | | | | | | | | | | | | | | This patch adds new three helper functions to copy data between an SG list and a linear buffer. - sg_copy_from_buffer copies data from linear buffer to an SG list - sg_copy_to_buffer copies data from an SG list to a linear buffer When the APIs copy data from a linear buffer to an SG list, flush_kernel_dcache_page is called. It's not necessary for everyone but it's a no-op on most architectures and in general the API is not used in performance critical path.

* [SCSI] scsi_error: add target reset handlerMike Christie2008-04-07
| | | | | | | | | | | | | | | | The problem is that serveral drivers are sending a target reset from the device reset handler, and if we have multiple devices a target reset gets sent for each device when only one would be sufficient. And if we do a target reset it affects all the commands on the target so the device reset handler code only cleaning up one devices's commands makes programming the driver a little more difficult than it should be. This patch adds a target reset handler, which drivers can use to send a target reset. If successful it cleans up the commands for a devices accessed through that starget.

* [SCSI] st: add option to use SILI in variable block readsKai Makisara2008-04-07
| | | | | | | | | | | Add new option MT_ST_SILI to enable setting the SILI bit in reads in variable block mode. If SILI is set, reading a block shorter than the byte count does not result in CHECK CONDITION. The length of the block is determined using the residual count from the HBA. Avoiding the REQUEST SENSE command for every block speeds up some real applications considerably.

* | cgroups: add cgroup support for enabling controllers at boot timePaul Menage2008-04-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The effects of cgroup_disable=foo are: - foo isn't auto-mounted if you mount all cgroups in a single hierarchy - foo isn't visible as an individually mountable subsystem As a result there will only ever be one call to foo->create(), at init time; all processes will stay in this group, and the group will never be mounted on a visible hierarchy. Any additional effects (e.g. not allocating metadata) are up to the foo subsystem. This doesn't handle early_init subsystems (their "disabled" bit isn't set be, but it could easily be extended to do so if any of the early_init systems wanted it - I think it would just involve some nastier parameter processing since it would occur before the command-line argument parser had been run. Hugh said: Ballpark figures, I'm trying to get this question out rather than processing the exact numbers: CONFIG_CGROUP_MEM_RES_CTLR adds 15% overhead to the affected paths, booting with cgroup_disable=memory cuts that back to 1% overhead (due to slightly bigger struct page). I'm no expert on distros, they may have no interest whatever in CONFIG_CGROUP_MEM_RES_CTLR=y; and the rest of us can easily build with or without it, or apply the cgroup_disable=memory patches.

This problem was introduced by commit fb56dbb31c4738a3918db81fd24da732ce3b4ae6 Author: Avi Kivity <avi@qumranet.com> Date: Sun Dec 2 10:50:06 2007 +0200 KVM: Export include/linux/kvm.h only if $ARCH actually supports KVM Currently, make headers_check barfs due to <asm/kvm.h>, which <linux/kvm.h> includes, not existing. Rather than add a zillion <asm/kvm.h>s, export kvm. only if the arch actually supports it. Signed-off-by: Avi Kivity <avi@qumranet.com> which makes this an 2.6.25 regression. One way of solving the issue is to enhance Kbuild, but Avi and David conviced me, that changing headers_install is not the way to go. This patch changes the definition for linux/kvm.h to unifdef-y. If  unifdef-y is used for linux/kvm.h "make headers_check" will fail on all architectures without asm/kvm.h. Therefore, this patch also provides asm/kvm.h on all architectures.

Call with all locks already taken (by do_umount()) and leave calling release_mounts() to caller (it will do release_mounts() anyway, so we can just put into the same list).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes the use of GPIO routines which are in the PCI configuration space of the RDC321x, therefore reading/writing to this space without spinlock protection can be problematic. We also now request and free GPIOs and support the MGB100 board, previous code was very AR525W-centric.
