* [SCSI] lpfc 8.3.24: Miscellaneous Fixes and CorrectionsJames Smart2011-05-261-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | Miscellaneous Fixes and Corrections - Remove the memset in the lpfc_sli4_remove_rpi_hdrs call. - Correct swapping of SGE word 2 relative to offset value - Reorganize CQ and EQ usage to comply with SLI4 Specification. - Expand the driver to check the rn bit. Only detect an error if the error bit is set and the RN bit is NOT set. - If mailbox completion code is not success AND the mailbox status is success, then and only then will the driver overwrite the mailbox status. - When driver initializing device, if the device is on a PCIe bus, set PCI's "needs fundamental reset" bit so that EEH uses fundamental reset instead of hot reset for recovery. - Prevent driver from using new WWN when changed in firmware (until driver reload) - When HBA reports maximum SGE size > 0xffffffff (infinite), override with 0x80000000. - Fixed potential missed SLI4 device initialization failure conditions. - Added 100ms delay before driver action following IF_TYPE_2 function reset. - Reverted patch to UNREG/REG on PLOGI to mapped/unmapped node. - Add a check for the CVL received flag in the fcf inuse routine to avoid unregistering the fcf if Devloss fires before Delay discover timer fires.

* 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.

* debugfs: Fix terminology inconsistency of dir name to mount debugfs filesystem.GeunSik Lim2009-06-151-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many developers use "/debug/" or "/debugfs/" or "/sys/kernel/debug/" directory name to mount debugfs filesystem for ftrace according to ./Documentation/tracers/ftrace.txt file. And, three directory names(ex:/debug/, /debugfs/, /sys/kernel/debug/) is existed in kernel source like ftrace, DRM, Wireless, Documentation, Network[sky2]files to mount debugfs filesystem. debugfs means debug filesystem for debugging easy to use by greg kroah hartman. "/sys/kernel/debug/" name is suitable as directory name of debugfs filesystem. - debugfs related reference: http://lwn.net/Articles/334546/ Fix inconsistency of directory name to mount debugfs filesystem. * From Steven Rostedt - find_debugfs() and tracing_files() in this patch.

| | | | | | | | | | | | | | | Preps the organization of the driver so that the bottom half, which interacts with the hardware, can share common code sequences for attachment, detachment, initialization, teardown, etc with new hardware. For very common code sections, which become specific to the interface type, the driver uses an indirect function call. The function is set at initialization. For less common sections, such as initialization, the driver looks at the interface type and calls the routines relative to the interface.
