drivers/scsi/ch.c: don't use vprintk as macro

2010-08-11T15:59:01Z

It's an exported symbol of kernel/printk.c Rename vprintk and dprintk macros to more common VPRINTK and DPRINTK Add do { } while(0) around macros Add level to VPRINTK so KERN_CONT can be used a couple of times.

drivers/scsi/aic94xx/aic94xx_init.c: correct the size argument to kmalloc

2010-08-11T15:59:00Z

In each case, the destination of the allocation has type struct **, so the elements of the array should have pointer type, not structure type. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // @disable sizeof_type_expr@ type T; T **x; @@ x = <+...sizeof( - T + *x )...+> // Signed-off-by: Julia Lawall Cc: Rolf Eike Beer Cc: Joe Perches Cc: James Bottomley Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h

2010-03-30T13:02:32Z

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.

[SCSI] ch: Add scsi type modalias

2009-03-13T20:48:43Z

The ch module is missing the scsi:t-0x08* alias that would cause it to be auto-loaded when a device of that type if found by udev, requiring udev to have a specific rule just for this one module. This patch adds the alias. Signed-off-by: Scott James Remnant Signed-off-by: James Bottomley

[SCSI] add residual argument to scsi_execute and scsi_execute_req

2008-12-29T17:24:24Z

scsi_execute() and scsi_execute_req() discard the residual length information. Some callers need it. This adds residual argument (optional) to scsi_execute and scsi_execute_req. Signed-off-by: FUJITA Tomonori Signed-off-by: James Bottomley

[SCSI] ch: fix ch_remove oops

2008-07-26T19:17:47Z

The following commit causes ch_remove oops: commit 24b42566c3fcbb5a9011d1446783d0f5844ccd45 Author: Greg Kroah-Hartman Date: Fri May 16 17:55:12 2008 -0700 SCSI: fix race in device_create There is a race from when a device is created with device_create() and then the drvdata is set with a call to dev_set_drvdata() in which a sysfs file could be open, yet the drvdata will be NULL, causing all sorts of bad things to happen. This patch fixes the problem by using the new function, device_create_drvdata(). It fixes the problem in all of the scsi drivers that need it. Cc: Kay Sievers Cc: Doug Gilbert Cc: James E.J. Bottomley Signed-off-by: Greg Kroah-Hartman The problem is ch_probe stores ch's private data at a wrong place. We need to store it at scsi_device->sdev_gendev but the above patch stores it at device struct that device_create_drvdata returns. So we hit an oops when ch_remove accesses scsi_device->sdev_gendev->driver_data, which is NULL. Actually, there wasn't a race because ch doesn't create sysfs files with device struct that device_create returns. This patch puts back dev_set_drvdata() to set ch's private data properly.
