2010-04-26i2o: cleanup some exit pathsDan Carpenter1-10/+6
This is just a cleanup and doesn't change how the code works. The original code had a mix of returns and gotos so I changed everything to just return directly.

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.hTejun Heo10-0/+10
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.

2010-02-17[SCSI] fusion: hold off error recovery while alternate ioc is initializingMichael Reed1-6/+11
After discussing this patch with LSI, I resubmitting with a recommended 40 second wait for the alternate ioc's initialization to complete. -- Fusion FC chips are two function with some shared resources. During initialization of one function its driver inhibits the ability of the other function's driver to allocate message frames by clearing its "active" flag. Should mid-layer error recovery be initiated for a scsi command during this initialization (which can take up to 40 seconds) error recovery will escalate to the level of host reset. This host reset might fail (as the other function is resetting) resulting in all connected targets being taken offline. This patch holds off mid-layer error recovery for up to 40 seconds to permit initialization of the other function to complete.

2009-09-12[SCSI] mptsas : FW event thread and scsi mid layer deadlock in SYNCHRONIZE CACHE commandKashyap, Desai1-7/+1
Normally In HBA reset path MPT driver will flush existing work in current work queue (mpt/0) . This is just a dummy activity for MPT driver point of view, since HBA reset will turn off Work queue events. It means we will simply returns from work queue without doing anything. But for the case where Work is already done (half the way), we have to have that work to be done. Considering above condition we stuck forever since Deadlock in scsi midlayer and MPT driver. sd_sync_cache() will wait forever since HBA is not in Running state, and it will never come into Running state since sd_sync_cache() is called from HBA reset context. Now new code will not wait for half cooked work to be finished before returning from HBA reset. Once we are out of HBA reset, EH thread will change host state to running from recovery and work waiting for running state of HBA will be finished.
