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). This patch enable me to add such to just the new helper function instead of touching two functions, sdebug_add_adapter and devInfoReg.

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. The patch is against lk 2.6.20-rc3 . The version is bumped to 1.81 . 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.

See http://www.torque.net/sg/sdebug26.html for more information on the scsi_debug driver. ChangeLog: - add 'vpd_use_hostno' parameter to allow simulated hosts to see the same set of targets (and luns). For testing multipath software. - add 'fake_rw' parameter to ignore the data in READ and WRITE commands - add support for log subpages (new in SPC-4) - yield appropriate block descriptor for MODE SENSE commands (only for pdt=0 (i.e. disks)) - REQUEST SENSE response no longer shows the stopped power condition (SAT changed to agree with SPC-3) Signed-off-by: NDouglas Gilbert <dougg@torque.net> Signed-off-by: NJames Bottomley <James.Bottomley@SteelEye.com>
