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": "5e31d76f2817bd50258a092a7c5b15b3006fd61c", "tree": "736c73c564635d767a1592cc540a23695b96c6a3", "parents": [ "0933e2d98d1b170ef62d48e18157f5dc43b58217" ], "author": { "name": "Kay Sievers", "email": "kay.sievers@vrfy.org", "time": "Wed Jan 13 14:16:36 2010 +0100" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Sun Mar 07 17:04:48 2010 -0800" }, "message": "Driver-Core: devtmpfs - reset inode permissions before unlinking\n\nBefore unlinking the inode, reset the current permissions of possible\nreferences like hardlinks, so granted permissions can not be retained\nacross the device lifetime by creating hardlinks, in the unusual case\nthat there is a user-writable directory on the same filesystem.\n\nSigned-off-by: Kay Sievers \u003ckay.sievers@vrfy.org\u003e\nCc: stable \u003cstable@kernel.org\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n" }, { "commit": "f776c5ec4690b21b3668ad5956774a22c86f541a", "tree": "b634878d93ff3a3683240a138e5f2bca18d64733", "parents": [ "24bc7347da73a9ed3383056c3d0f28c0e361621e" ], "author": { "name": "Heiko Carstens", "email": "heiko.carstens@de.ibm.com", "time": "Mon Jan 18 14:36:12 2010 +0100" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Wed Jan 20 15:02:05 2010 -0800" }, "message": "driver-core: fix devtmpfs crash on s390\n\nOn Mon, Jan 18, 2010 at 05:26:20PM +0530, Sachin Sant wrote:\n\u003e Hello Heiko,\n\u003e\n\u003e Today while trying to boot next-20100118 i came across\n\u003e the following Oops :\n\u003e\n\u003e Brought up 4 CPUs\n\u003e Unable to handle kernel pointer dereference at virtual kernel address 0000000000\n\u003e 543000\n\u003e Oops: 0004 #1 SMP\n\u003e Modules linked in:\n\u003e CPU: 0 Not tainted 2.6.33-rc4-autotest-next-20100118-5-default #1\n\u003e Process swapper (pid: 1, task: 00000000fd792038, ksp: 00000000fd797a30)\n\u003e Krnl PSW : 0704200180000000 00000000001eb0b8 (shmem_parse_options+0xc0/0x328)\n\u003e R:0 T:1 IO:1 EX:1 Key:0 M:1 W:0 P:0 AS:0 CC:2 PM:0 EA:3\n\u003e Krnl GPRS: 000000000054388a 000000000000003d 0000000000543836 000000000000003d\n\u003e 0000000000000000 0000000000483f28 0000000000536112 00000000fd797d00\n\u003e 00000000fd4ba100 0000000000000100 0000000000483978 0000000000543832\n\u003e 0000000000000000 0000000000465958 00000000001eb0b0 00000000fd797c58\n\u003e Krnl Code: 00000000001eb0aa: c0e5000994f1 brasl %r14,31da8c\n\u003e 00000000001eb0b0: b9020022 ltgr %r2,%r2\n\u003e 00000000001eb0b4: a784010b brc 8,1eb2ca\n\u003e \u003e00000000001eb0b8: 92002000 mvi 0(%r2),0\n\u003e 00000000001eb0bc: a7080000 lhi %r0,0\n\u003e 00000000001eb0c0: 41902001 la %r9,1(%r2)\n\u003e 00000000001eb0c4: b9040016 lgr %r1,%r6\n\u003e 00000000001eb0c8: b904002b lgr %r2,%r11\n\u003e Call Trace:\n\u003e (\u003c00000000fd797c50\u003e 0xfd797c50)\n\u003e \u003c00000000001eb5da\u003e shmem_fill_super+0x13a/0x25c\n\u003e \u003c0000000000228cfa\u003e get_sb_single+0xbe/0xdc\n\u003e \u003c000000000034ffc0\u003e dev_get_sb+0x2c/0x38\n\u003e \u003c000000000066c602\u003e devtmpfs_init+0x46/0xc0\n\u003e \u003c000000000066c53e\u003e driver_init+0x22/0x60\n\u003e \u003c000000000064d40a\u003e kernel_init+0x24e/0x3d0\n\u003e \u003c000000000010a7ea\u003e kernel_thread_starter+0x6/0xc\n\u003e \u003c000000000010a7e4\u003e kernel_thread_starter+0x0/0xc\n\u003e\n\u003e I never tried to boot a kernel with DEVTMPFS enabled on a s390 box.\n\u003e So am wondering if this is supported or not ?
