Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability. As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n only the necessary includes are there. ie. if only gfp is used,\n gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n blocks and try to put the new include such that its order conforms\n to its surrounding. It\u0027s put in the include block which contains\n core kernel includes, in the same order that the rest are ordered -\n alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n because the file doesn\u0027t have fitting include block), it prints out\n an error message indicating which .h file needs to be added to the\n file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n and ~3000 slab.h inclusions. The script emitted errors for ~400\n files.\n\n2. Each error was manually checked. Some didn\u0027t need the inclusion,\n some needed manual addition while adding it to implementation .h or\n embedding .c file was more appropriate for others. This step added\n inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n editing them as sprinkling gfp.h and slab.h inclusions around .h\n files could easily lead to inclusion dependency hell. Most gfp.h\n inclusion directives were ignored as stuff from gfp.h was usually\n wildly available and often used in preprocessor macros. Each\n slab.h inclusion directive was examined and added manually as\n necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7. Build test were done on the following configurations and failures\n were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my\n distributed build env didn\u0027t work with gcov compiles) and a few\n more options had to be turned off depending on archs to make things\n build (like ipr on powerpc/64 which failed due to missing writeq).\n\n * x86 and x86_64 UP and SMP allmodconfig and a custom test config.\n * powerpc and powerpc64 SMP allmodconfig\n * sparc and sparc64 SMP allmodconfig\n * ia64 SMP allmodconfig\n * s390 SMP allmodconfig\n * alpha SMP allmodconfig\n * um on x86_64 SMP allmodconfig\n\n8. percpu.h modifications were reverted so that it could be applied as\n a separate patch and serve as bisection point.\n\nGiven the fact that I had only a couple of failures from tests on step\n6, I\u0027m fairly confident about the coverage of this conversion patch.\nIf there is a breakage, it\u0027s likely to be something in one of the arch\nheaders which should be easily discoverable easily on most builds of\nthe specific arch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nGuess-its-ok-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\n" }, { "commit": "382f51fe2f2276344d8a21447656778cdf6583b6", "tree": "c2836a2cca4126c9c026ce5aa2fdf9f1c8ccded6", "parents": [ "701791cc3c8fc6dd83f6ec8af7e2541b4a316606", "54987386ee3790f3900de4df2ed4deb0e18dfc9f" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Dec 09 19:42:25 2009 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Dec 09 19:42:25 2009 -0800" }, "message": "Merge git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi-misc-2.6\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi-misc-2.6: (222 commits)\n [SCSI] zfcp: Remove flag ZFCP_STATUS_FSFREQ_TMFUNCNOTSUPP\n [SCSI] zfcp: Activate fc4s attributes for zfcp in FC transport class\n [SCSI] zfcp: Block scsi_eh thread for rport state BLOCKED\n [SCSI] zfcp: Update FSF error reporting\n [SCSI] zfcp: Improve ELS ADISC handling\n [SCSI] zfcp: Simplify handling of ct and els requests\n [SCSI] zfcp: Remove ZFCP_DID_MASK\n [SCSI] zfcp: Move WKA port to zfcp FC code\n [SCSI] zfcp: Use common code definitions for FC CT structs\n [SCSI] zfcp: Use common code definitions for FC ELS structs\n [SCSI] zfcp: Update FCP protocol related code\n [SCSI] zfcp: Dont fail SCSI commands when transitioning to blocked fc_rport\n [SCSI] zfcp: Assign scheduled work to driver queue\n [SCSI] zfcp: Remove STATUS_COMMON_REMOVE flag as it is not required anymore\n [SCSI] zfcp: Implement module unloading\n [SCSI] zfcp: Merge trace code for fsf requests in one function\n [SCSI] zfcp: Access ports and units with container_of in sysfs code\n [SCSI] zfcp: Remove suspend callback\n [SCSI] zfcp: Remove global config_mutex\n [SCSI] zfcp: Replace local reference counting with common kref\n ...\n" }, { "commit": "e881a172dac4d9ea3b2a1540041d872963c269bd", "tree": "9eb1f344b107806c0041c4e0a64192a055117289", "parents": [ "dbf9bfe615717d1145f263c0049fe2328e6ed395" ], "author": { "name": "Mike Christie", "email": "michaelc@cs.wisc.edu", "time": "Thu Oct 15 17:46:39 2009 -0700" }, "committer": { "name": "James Bottomley", "email": "James.Bottomley@suse.de", "time": "Fri Dec 04 12:00:41 2009 -0600" }, "message": "[SCSI] modify change_queue_depth to take in reason why it is being called\n\nThis patch modifies scsi_host_template-\u003echange_queue_depth so that\nit takes an argument indicating why it is being called.

This duality creates some\nheadaches.\n\nFirst of all, block layer and low level drivers can\u0027t really determine\nwhat rq-\u003edata_len contains while a request is executing. It could be\nthe total request length or it coulde be anything else one of the\nlower layers is using to keep track of residual count. This\ncomplicates things because blk_rq_bytes() and thus\n[__]blk_end_request_all() relies on rq-\u003edata_len for PC commands.\nDrivers which want to report residual count should first cache the\ntotal request length, update rq-\u003edata_len and then complete the\nrequest with the cached data length.\n\nSecondly, it makes requests default to reporting full residual count,\nie. reporting that no data transfer occurred. The residual count is\nan exception not the norm; however, the driver should clear\nrq-\u003edata_len to zero to signify the normal cases while leaving it\nalone means no data transfer occurred at all.

However, as of 2.5, the block layer has a\ndma_alignment variable which ensures both the beginning and length of a\nDMA transfer are aligned on the dma_alignment boundary. Although the\nblock layer does adjust the beginning of the transfer to ensure this\nhappens, it doesn\u0027t actually adjust the length, it merely makes sure\nthat space is allocated for transfers beyond the declared length. The\nupshot of this is that scatterlists may be padded to any size between\nthe actual length and the length adjusted to the dma_alignment safely\nknowing that memory is allocated in this region.\n\nRight at the moment, SCSI takes the default dma_aligment which is on a\n512 byte boundary. Note that this aligment only applies to transfers\ncoming in from user space. However, since all kernel allocations are\nautomatically aligned on a minimum of 32 byte boundaries, it is safe to\nadjust them in this manner as well.\n\ntj: * Adjusting sg after padding is done in block layer.
