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": "086fa5ff0854c676ec333760f4c0154b3b242616", "tree": "ee63fb3c7c7d964bd799355b7cde18ba95f91f07", "parents": [ "eb28d31bc97e6374d81f404da309401ffaed467b" ], "author": { "name": "Martin K.

The logic behind it was to be softer to devices;\nhowever, this doesn\u0027t really help much. Rationales for the change:\n\n* BIOS may freeze lock certain things during boot and softreset can\u0027t\n unlock those. This by itself is okay but during operation PHY event\n or other error conditions can trigger hardreset and the device may\n end up with different configuration.\n\n For example, after a hardreset, previously unlockable HPA can be\n unlocked resulting in different device size and thus revalidation\n failure. Similar condition can occur during or after resume.\n\n* Certain ATAPI devices require hardreset to recover after certain\n error conditions. On PATA, this is done by issuing the DEVICE RESET\n command. On SATA, COMRESET has equivalent effect. The problem is\n that DEVICE RESET needs its own execution protocol.\n\n For SFF controllers with bare TF access, it can be easily\n implemented but more advanced controllers (e.g. ahci and sata_sil24)\n require specialized implementations. Simply using hardreset solves\n the problem nicely.\n\n* COMRESET initialization sequence is the norm in SATA land and many\n SATA devices don\u0027t work properly if only SRST is used. For example,\n some PMPs behave this way and libata works around by always issuing\n hardreset if the host supports PMP.\n\n Like the above example, libata has developed a number of mechanisms\n aiming to promote softreset to hardreset if softreset is not going\n to work. This approach is time consuming and error prone.\n\n Also, note that, dependingon how you read the specs, it could be\n argued that PMP fan-out ports require COMRESET to start operation.\n In fact, all the PMPs on the market except one don\u0027t work properly\n if COMRESET is not issued to fan-out ports after PMP reset.\n\n* COMRESET is an integral part of SATA connection and any working\n device should be able to handle COMRESET properly. After all, it\u0027s\n the way to signal hardreset during reboot. This is the most used\n and recommended (at least by the ahci spec) method of resetting\n devices.\n\nSo, this patch makes libata prefer hardreset over softreset by making\nthe following changes.\n\n* Rename ATA_EH_RESET_MASK to ATA_EH_RESET and use it whereever\n ATA_EH_{SOFT|HARD}RESET used to be used. ATA_EH_{SOFT|HARD}RESET is\n now only used to tell prereset whether soft or hard reset will be\n issued.\n\n* Strip out now unneeded promote-to-hardreset logics from\n ata_eh_reset(), ata_std_prereset(), sata_pmp_std_prereset() and\n other places.\n\nSigned-off-by: Tejun Heo \u003chtejun@gmail.com\u003e\n" }, { "commit": "526917641aa50eb852591cc3953a92374bedc836", "tree": "38d2033ed637a54ff607e4c1adf861fb3b90f44a", "parents": [ "a34c4e98367965402134f2e66c3cdc4416f109e4" ], "author": { "name": "FUJITA Tomonori", "email": "fujita.tomonori@lab.ntt.co.jp", "time": "Tue Mar 25 09:26:51 2008 +0900" }, "committer": { "name": "James Bottomley", "email": "James.Bottomley@HansenPartnership.com", "time": "Mon Apr 07 12:19:02 2008 -0500" }, "message": "[SCSI] libata: use scsi_build_sense_buffer\n\nSigned-off-by: FUJITA Tomonori \u003cfujita.tomonori@lab.ntt.co.jp\u003e\nCc: Jeff Garzik \u003cjeff@garzik.org\u003e\nCc: Tejun Heo \u003chtejun@gmail.com\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@HansenPartnership.com\u003e\n" }, { "commit": "aacda37538e7f9cf2148eedf3766239829e51ba4", "tree": "0206d2db8ce636aadabf8e3effd1ee3114ccff2a", "parents": [ "cc7feea39bed2951cc29af3ad642f39a99dfe8d3" ], "author": { "name": "Tejun Heo", "email": "htejun@gmail.com", "time": "Tue Mar 18 17:47:43 2008 +0900" }, "committer": { "name": "Jeff Garzik", "email": "jeff@garzik.org", "time": "Mon Mar 24 22:09:12 2008 -0400" }, "message": "libata: implement ata_qc_raw_nbytes()\n\nImplement ata_qc_raw_nbytes() which determines the raw user-requested\nsize of a PC command.\n\nSigned-off-by: Tejun Heo \u003chtejun@gmail.com\u003e\nSigned-off-by: Jeff Garzik \u003cjeff@garzik.org\u003e\n" }, { "commit": "e3790c7d42a545e8fe8b38b513613ca96687b670", "tree": "0b849ba46007c4d7f7a34271a76d58e7406cbad7", "parents": [ "7a85f8896f4b4a4a0249563b92af9e3161a6b467" ], "author": { "name": "Tejun Heo", "email": "htejun@gmail.com", "time": "Tue Mar 04 11:18:17 2008 +0100" }, "committer": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Tue Mar 04 11:18:17 2008 +0100" }, "message": "block: separate out padding from alignment\n\nBlock layer alignment was used for two different purposes - memory\nalignment and padding.

For standard\nNCQ/non-NCQ exclusion, ata_std_qc_defer() is implemented. ahci and\nsata_sil24 are converted to use ata_std_qc_defer().\n\nops-\u003eqc_defer() is heavier than the original mechanism because full qc\nis prepped before determining to defer it, but various information is\nneeded to determine defer conditinos and fully translating a qc is the\nonly way to supply such information in generic manner.\n\nIMHO, this shouldn\u0027t cause any noticeable performance issues as\n\n* for most cases deferring occurs rarely (except for NCQ-aware\n cmd-switching PMP)\n* translation itself isn\u0027t that expensive\n* once deferred the command won\u0027t be repeated until another command\n completes which usually is a very long time cpu-wise.\n\nSigned-off-by: Tejun Heo \u003chtejun@gmail.com\u003e\nSigned-off-by: Jeff Garzik \u003cjeff@garzik.org\u003e\n" }, { "commit": "854c73a2f1c3bcc4aa88c25e208dc597e8efb795", "tree": "210569f3c4fa4f9413ceb0bc3fcf89648a9894b2", "parents": [ "c78968bb0f7714ceba1cdfa23714454fc98cefdf" ], "author": { "name": "Tejun Heo", "email": "htejun@gmail.com", "time": "Sun Sep 23 13:14:11 2007 +0900" }, "committer": { "name": "Jeff Garzik", "email": "jeff@garzik.org", "time": "Fri Oct 12 14:55:40 2007 -0400" }, "message": "libata: misc updates for AN\n\nUpdate AN support in preparation of PMP support.\n\n* s/ata_id_has_AN/ata_id_has_atapi_AN/\n* add AN enabled reporting during configuration\n* add err_mask to AN configuration failure reporting\n* update LOCKING comment for ata_scsi_media_change_notify()\n* check whether ATA dev is attached to SCSI dev ata_scsi_media_change_notify()\n* set ATA_FLAG_AN in ahci and sata_sil24\n\nSigned-off-by: Tejun Heo \u003chtejun@gmail.com\u003e\nCc: Kriten Carlson Accardi \u003ckristen.c.accardi@intel.com\u003e\nSigned-off-by: Jeff Garzik \u003cjeff@garzik.org\u003e\n" }, { "commit": "c78968bb0f7714ceba1cdfa23714454fc98cefdf", "tree": "cbf066559205ce0d00829c74a406f3a2140623e4", "parents": [ "24f756866676b40446e361c1f87738707161da93" ], "author": { "name": "Jeff Garzik", "email": "jeff@garzik.org", "time": "Fri Sep 21 21:03:28 2007 -0400" }, "committer": { "name": "Jeff Garzik", "email": "jeff@garzik.org", "time": "Fri Oct 12 14:55:40 2007 -0400" }, "message": "[libata] SCSI: simulator version, not device version, belongs in VPD\n\nSigned-off-by: Jeff Garzik \u003cjeff@garzik.org\u003e\n" }, { "commit": "24f756866676b40446e361c1f87738707161da93", "tree": "2709ec5b4bb5f0e9c980621e7a1a2b97bdcd7a93", "parents": [ "00bd02027fc4a5cf92a3e538896b3642b40515df" ], "author": { "name": "Jeff Garzik", "email": "jeff@garzik.org", "time": "Fri Sep 21 07:54:49 2007 -0400" }, "committer": { "name": "Jeff Garzik", "email": "jeff@garzik.org", "time": "Fri Oct 12 14:55:40 2007 -0400" }, "message": "[libata] SCSI: clean up R/W recovery mode page\n\nClear ARRE, we don\u0027t do auto-reallocation on reads, just on writes.\n\nAlso, hardcode the size of the array using RW_RECOVERY_MPAGE_LEN,\nfollowing the style of the surrounding code.\n\nSigned-off-by: Jeff Garzik \u003cjeff@garzik.org\u003e\n" }, { "commit": "00bd02027fc4a5cf92a3e538896b3642b40515df", "tree": "e5e2a72a467577a5a65be5886f96039c2f62a8af", "parents": [ "453941455218a81eedcea5dbafa38b8815920a8c" ], "author": { "name": "Jeff Garzik", "email": "jeff@garzik.org", "time": "Fri Sep 21 07:26:08 2007 -0400" }, "committer": { "name": "Jeff Garzik", "email": "jeff@garzik.org", "time": "Fri Oct 12 14:55:40 2007 -0400" }, "message": "[libata] SCSI: improve FORMAT UNIT; minor code cleanups\n\n* SAT specifies that FORMAT UNIT should be translated into a series\n of READ and WRITE commands that zero the ATA device.
