2009-12-04[SCSI] scsi_debug: fix Thin provisioning supportDouglas Gilbert1-4/+9
While testing scsi_debug with these patches I found a problem with the Block Limits VPD page function. The length returned by the inquiry_evpd_b0() function was too short. A patch to fix that and a cosmetic change (that the form factor of scsi_debug is less than 1.8 inches) is attached.

2009-12-04[SCSI] scsi_debug: Thin provisioning supportMartin K. Petersen1-3/+335
This version fixes 64-bit modulo on 32-bit as well as inadvertent map updates when TP was disabled. Implement support for thin provisioning in scsi_debug. No actual memory de-allocation is taking place. The intent is to emulate a thinly provisioned storage device, not to be one. There are four new module options: - unmap_granularity specifies the granularity at which to track mapped blocks (specified in number of logical blocks). 2048 (1 MB) is a realistic value for disk arrays although some may have a finer granularity. - unmap_alignment specifies the first LBA which is naturally aligned on an unmap_granularity boundary. - unmap_max_desc specifies the maximum number of ranges that can be unmapped using one UNMAP command. If this is 0, only WRITE SAME is supported and UNMAP will cause a check condition. - unmap_max_blocks specifies the maximum number of blocks that can be unmapped using a single UNMAP command. Default is 0xffffffff. These parameters are reported in the new and extended block limits VPD. If unmap_granularity is specified the device is tagged as thin provisioning capable in READ CAPACITY(16). A bitmap is allocated to track whether blocks are mapped or not. A WRITE request will cause a block to be mapped. So will WRITE SAME unless the UNMAP bit is set. Blocks can be unmapped using either WRITE SAME or UNMAP. No accounting is done to track partial blocks. This means that only whole blocks will be marked free. This is how the array people tell me their firmwares work. GET LBA STATUS is also supported. This command reports whether a block is mapped or not, and how long the adjoining mapped/unmapped extent is. The block allocation bitmap can also be viewed from user space via: /sys/bus/pseudo/drivers/scsi_debug/map Signed-off-by: Martin K.

Two functions, sdebug_add_adapter and devInfoReg, creates new scsi_debug devices. To simplify the code, this patch adds a new helper function to create new scsi_debug devices (sdebug_device_create) and converts both functions to use it. I plan to add more to scsi_debug devices (e.g. using a thread for a scsi_debug device for scalability testings).

2007-02-14[PATCH] remove many unneeded #includes of sched.hTim Schmielau1-1/+0
After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

After discussions in the thread titled: [PATCH] scsi_debug: illegal blocking memory allocation here is a patch containing the discussed fix and some other fixes and additions.

ChangeLog: - Change several GFP_KERNEL allocations to GFP_ATOMIC as they can be called from queuecommand() context - check above allocation returns and if out of memory report DID_REQUEUE in two cases, DID_NO_CONNECT in another, and fail slave configure() in another - add support for WRITE BUFFER command - add aborted_command error injection support (opts mask 0x10), similar mechanism to recovered_error injection.
