* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [SCSI] qla4xxx: add timeout handlerMike Christie2009-07-301-0/+17
| | | | | | | | | | | | | | | | | | | | | | Recently dm-multipath began calling blk_abort_queue. This causes all the commands/request running on the path to have the timeout function called. If a path does go down, and the LLD returns DID_*, dm-multpiath will eventually get this error and begin to call the cmd timeout handler. qla4xxx currently does not set a timed out handler and so the default one could return BLK_EH_NOT_HANDLED and end up firing the scsi eh and stopping IO to all paths on the host when only one path is affected. For software and offload iscsi we have a timed out handler already. This patch adds a driver specific one to qla4xxx because there are some ddb->state and session->state and command completion races that are better handled in the LLD. This also handles the problem where if the session is down, we do not need the scsi eh to run until the transport code has tried to reconnect us.

| | | | | | | | | | | | | | | | Qla4xxx can just call the iscsi recovery functions directly. There is no need for userspace to do this for qla4xxx, because we do not use the mutex to iterate over devices anymore and iscsi_block /unblock_session can be called from interrupt context or the dpc thread. And having userspace do this just creates uneeded headaches for qla4xxx root situations where the session may experience problems. For example during the kernel shutdown the scsi layer wants to send sync caches, but at this time userspace is not up (iscsid is not running), so we cannot recover from the problem.

* [SCSI] qla4xxx: ql4_os.c bugfixesDavid C Somayajulu2007-05-261-4/+13
| | | | | | | | | | | | | | Free memory resources after invoking free_irq() in qla4xxx_free_adapter(). QLA4xxx has two pci functions per port (Ethernet and iSCSI). When one of these PCI functions issues a HBA reset, all other functions are notified and need to acknowledge and re-initialize. During module qla4xxx_remove_adapter() gets invoked. This function needs to wait if it is currently responding to a reset from another function.

* [SCSI] qla4xxx: bug fixesDavid C Somayajulu2007-01-271-25/+39
| | | | | | | | | | | | | | | | | The included patch fixes the following issues: 1. qla3xxx/qla4xxx co-existence issue which can result in a lockup when qla3xxx driver is unloaded, or when ifdown; ifup is performed on one of the interfaces correponding to qla3xxx. This is because qla4xxx HBA supports one ethernet and iscsi interfaces per port. Both iscsi and ethernet interfaces share the same state machine. The problem has to do with synchronizing access to the state machine in the event of a reset 2. mutex_lock() is sometimes not followed by mutex_unlock() prior to invoking a msleep() in qla4xxx_mailbox_command() Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
