values The [vk][cmz]alloc(_node) family of functions return void pointers which it's completely unnecessary/pointless to cast to other pointer types since that happens implicitly.

2010-11-16SCSI host lock push-downJeff Garzik
Move the mid-layer's ->queuecommand() invocation from being locked with the host lock to being unlocked to facilitate speeding up the critical path for drivers who don't need this lock taken anyway. The patch below presents a simple SCSI host lock push-down as an equivalent transformation. No locking or other behavior should change with this patch. All existing bugs and locking orders are preserved. Additionally, add one parameter to queuecommand, struct Scsi_Host * and remove one parameter from queuecommand, void (*done)(struct scsi_cmnd *) Scsi_Host* is a convenient pointer that most host drivers need anyway, and 'done' is redundant to struct scsi_cmnd->scsi_done. Minimal code disturbance was attempted with this change. Most drivers needed only two one-line modifications for their host lock push-down.

2010-07-28[SCSI] aic7xxx: Remove OS utility wrappersPekka Enberg
This patch removes malloc(), free(), and printf() wrappers from the aic7xxx SCSI driver. I didn't use pr_debug for printf because of some 'clever' uses of printf don't compile with the pr_debug. I didn't fix the overeager uses of GFP_ATOMIC either because I wanted to keep this patch as simple as possible.

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo
implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

2009-04-03[SCSI] aic7xxx: leaves timer running on init failureHannes Reinecke
aic79xx leaves timers inserted when ahd_init() (which inserts two timers at its very end) succeeds but ahd_pci_map_int() fails. In this case ahd->init_level gets incremented to 5 only when that function succeeds, but ahd_free() calls ahd_shutdown() only when ahd->init_level == 5, and ahd_shutdown() is where the timers get removed. Since the freeing of the IRQ is not controlled by ahd->init_level, we should increment init_level prior to calling ahd_pci_map_int().

2008-02-23PM: Introduce PM_EVENT_HIBERNATE callback stateRafael J. Wysocki
During the last step of hibernation in the "platform" mode (with the help of ACPI) we use the suspend code, including the devices' ->suspend() methods, to prepare the system for entering the ACPI S4 system sleep state. But at least for some devices the operations performed by the ->suspend() callback in that case must be different from its operations during regular suspend. For this reason, introduce the new PM event type PM_EVENT_HIBERNATE and pass it to the device drivers' ->suspend() methods during the last phase of hibernation, so that they can distinguish this case and handle it as appropriate. Modify the drivers that handle PM_EVENT_SUSPEND in a special way and need to handle PM_EVENT_HIBERNATE in the same way. These changes are necessary to fix a hibernation regression related to the i915 driver (ref. http://lkml.org/lkml/2008/2/22/488). Signed-off-by: Rafael J.

The panic occurs if we get a MSGIN or MSGOUT for an unidentified SCB (meaning we didn't identify the outstanding command it was for). For MSGIN this is wrong because it could be an unsolicited negotiation MSGIN from the target. Still panic on unsolicited MSGOUT because this would represent a mistake in the negotiation phases. However, we should fix this as well. The specs say we should go to bus free for unexpected msgin. Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

2008-02-03scsi: fix dependency bug in aic7 MakefileSam Ravnborg
Building the aic7xxx driver includes the copy of an .h file from a _shipped file. In a highly parallel build Ingo saw that the build sometimes failed (included distcc usage). It was tracked down to a missing dependency from the .c source file to the generated .h file. We started to build the .c file before the copy (cat) operation of the .h file completed and we then only got half of the definitions from the copied .h file. Add an explicit dependency from the .c files to the generated .h files so make knows all dependencies and finsih the build of the .h files before it starts building the .o files. Ingo tested this fix and reported: good news: hundreds of successful kernel builds and no failures overnight.

2008-01-30[SCSI] remove use_sg_chainingJames Bottomley
With the sg table code, every SCSI driver is now either chain capable or broken (or has sg_tablesize set so chaining is never activated), so there's no need to have a check in the host template. Also tidy up the code by moving the scatterlist size defines into the SCSI includes and permit the last entry of the scatterlist pools not to be a power of two.

2008-01-30[SCSI] aic7xxx: fix ahc_done check SCB_ACTIVE for tagged transactionsDavid Milburn
The driver only needs to check the SCB_ACTIVE flag if the SCB is not in the untagged queue. If the driver is in error recovery, you may end panic'ing on a TUR that is in the untagged queue. Attempting to queue an ABORT message CDB: 0x0 0x0 0x0 0x0 0x0 0x0 SCB 3 done'd twice This patch is included in Adaptec's 6.3.11 driver on their website.

The commit de25deb18016f66dcdede165d07654559bb332bc changed scsi_cmnd.sense_buffer from a static array to a dynamically allocated buffer. We can't access to sense_buffer in '&cmd->sense_buffer' way.

2008-01-25[SCSI] aic7xxx: fix firmware buildVegard Nossum
This patch adds the proper $(obj) and $(src) prefixes to dependency rules in aic7xxx makefile. Without this patch, there is a remote possibility that parallel make with a different output directory can fail. Also changed the deprecated EXTRA_CFLAGS construct to ccflags-y syntax. Fixed up patch to survive "make drivers/scsi/ -j" with BUILD_FIRMWARE enable. /Sam Signed-off-by: Vegard Nossum <vegard.nossum@gmail.com> Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Acked-by: Hannes Reinecke <hare@suse.de> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
