* of: Remove duplicate fields from of_platform_driverGrant Likely2010-05-222-4/+10
| | | | | | | | | | | | | | | | .name, .match_table and .owner are duplicated in both of_platform_driver and device_driver. This patch is a removes the extra copies from struct of_platform_driver and converts all users to the device_driver members. This patch is a pretty mechanical change. The usage model doesn't change and if any drivers have been missed, or if anything has been fixed up incorrectly, then it will fail with a compile time error, and the fixup will be trivial. This patch looks big and scary because it touches so many files, but it should be pretty safe.

| * | | [SCSI] qla1280: retain firmware for error recoveryMichael Reed2010-03-271-52/+109
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The qla1280 driver acquires its firmware via udev. During boot the firmware is located in the initrd. If, after root is mounted, the adapter needs to reload firmware (host reset), the firmware load may fail if the root device is on the adapter being reset. This patch modifies qla1280 to retain the firmware loaded via the initial request_firmware() for use during error recovery.

| * | | [SCSI] advansys: fix regression with request_firmware changeHerton Ronaldo Krzesinski2010-03-271-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On newer kernels users of advansys module are reporting system hang when trying to load it without firmware files present. After looking closely at description on https://qa.mandriva.com/show_bug.cgi?id=53220, I think this is related to commit "[SCSI] advansys: use request_firmware". The problem is that after switch to request_firmware, asc_dvc->err_code isn't being set when firmware files aren't found or loading fails. err_code is used by the driver to judge if there was a fatal error or not, as can be seen for example on advansys_board_found, which will only return -ENODEV when err_code is set. Because err_code isn't being set when request_firmware fails, this is a change of behaviour of the code before request_firmware addition, making it continue to load and it fails later as the firmware wasn't really loaded.

As a result the session->state gets set to failed instead of in recovery. We end up not blocking the session and so the replacement timeout never gets started and we only end up failing the IO when scsi_softirq_done sees that the cmd has been running for (cmd->allowed + 1) * rq->timeout secs. We used to fail the IO right away so users are seeing a long delay when using dm-multipath. This problem was added in 2.6.28.

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.

It happen while in a mistake each request sent twice for the same vport. This interface is asynchronous, entering the delete request into a work queue, allowing more than one request to enter to the delete work queue. The result is a NULL pointer. The first request already delete the vport, while the second request got a pointer to the vport before the device destroyed. Re-create vport later cause system freeze. Solution: Check vport flags before entering the request to the work queue.

| * | | [SCSI] raid_attrs: fix dependency problemsJames Bottomley2010-03-032-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RAID attributes uses scsi_is_sdev_device() to gate some SCSI specific checking code. This causes two problems. Firstly if SCSI == n just defining scsi_is_sdev_device() to return false might not be enough to prevent gcc from emitting the code (and thus referring to undefined symbols), so this needs surrounding with an ifdef. Secondly, using scsi_is_sdev_device() when SCSI is either y or m gives a subtle problem in the m case: raid_attrs must also be m to use the symbol. Do the usual Kconfig jiggery-pokery to fix this.
