For cases where we can we can automatically prove that\nthe file offset is always ignored, we use noop_llseek, which maintains\nthe current behavior of not returning an error from a seek.\n\nNew drivers should normally not use noop_llseek but instead use no_llseek\nand call nonseekable_open at open time.

In the version that gets submitted upstream, the comments will\nbe gone and I will manually fix the indentation, because there does not\nseem to be a way to do that using coccinelle.\n\nSome amount of

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

This patch:\n * Introduces correct locking\n * Fixes i_nlink reference counting for inodes, when creating directories\n * Adds info printk, when hypfs filesystem has been mounted\n\nSigned-off-by: Michael Holzheu \u003cholzheu@de.ibm.com\u003e\nSigned-off-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nSigned-off-by: Heiko Carstens \u003cheiko.carstens@de.ibm.com\u003e\n" }, { "commit": "b01af5ba9105094ba4f1af60da8f7be44321a0c7", "tree": "68111e92125a498188e6cda64c32e1c8c032e738", "parents": [ "5693ce6f9b9f08942e55e3825db014f8b1205772" ], "author": { "name": "Michael Holzheu", "email": "holzheu@de.ibm.com", "time": "Fri Aug 10 14:32:27 2007 +0200" }, "committer": { "name": "Martin Schwidefsky", "email": "schwidefsky@de.ibm.com", "time": "Fri Aug 10 14:32:36 2007 +0200" }, "message": "[S390] hypfs: implement show_options\n\nSigned-off-by: Michael Holzheu \u003cholzheu@de.ibm.com\u003e\nSigned-off-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\n" }, { "commit": "c41d4e3e688e338418311f449a4c68f6cb8eabbb", "tree": "062f4431d9c2f3994009032eb32f3ad6877010d5", "parents": [ "3f0a6766e0cc5a577805732e5adb50a585c58175" ], "author": { "name": "Michael Holzheu", "email": "holzheu@de.ibm.com", "time": "Thu May 31 17:38:01 2007 +0200" }, "committer": { "name": "Martin Schwidefsky", "email": "schwidefsky@de.ibm.com", "time": "Thu May 31 17:38:10 2007 +0200" }, "message": "[S390] Add exception handler for diagnose 224\n\nTo be able to run with the diagnose 224 switched off, a potential\nspecification exception has to be handled.\n\nSigned-off-by: Michael Holzheu \u003cholzheu@de.ibm.com\u003e\nSigned-off-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\n" }, { "commit": "0b0bb3c6bd66bd28062a71c2ca3878d31e2081ee", "tree": "2c4569ea1836b739119c94b158ae6e98be76f042", "parents": [ "de5603748af8bf7deac403e6ba92887f8d18e812" ], "author": { "name": "Cornelia Huck", "email": "cornelia.huck@de.ibm.com", "time": "Thu May 10 15:45:41 2007 +0200" }, "committer": { "name": "Martin Schwidefsky", "email": "schwidefsky@de.ibm.com", "time": "Thu May 10 15:45:50 2007 +0200" }, "message": "[S390] fix subsystem removal fallout\n\nThis patch fixes compilation on s390 after the removal of\nstruct subsystem.\n\nSigned-off-by: Cornelia Huck \u003ccornelia.huck@de.ibm.com\u003e\nSigned-off-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\n" }, { "commit": "5dfe4c964a0dd7bb3a1d64a4166835a153146207", "tree": "2fb2fd8c09922be4f40a5a9ac50b537b1d780e27", "parents": [ "540473208f8ac71c25a87e1a2670c3c18dd4d6db" ], "author": { "name": "Arjan van de Ven", "email": "arjan@linux.intel.com", "time": "Mon Feb 12 00:55:31 2007 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Mon Feb 12 09:48:44 2007 -0800" }, "message": "[PATCH] mark struct file_operations const 2\n\nMany struct file_operations in the kernel can be \"const\".

An update can be triggered from user space through writing\n\u0027something\u0027 into a special purpose update file.\n\nWe create the following directory structure:\n\n\u003cmount-point\u003e/\n update\n cpus/\n \u003ccpu-id\u003e\n type\n mgmtime\n \u003ccpu-id\u003e\n ...\n hyp/\n type\n systems/\n \u003clpar-name\u003e\n cpus/\n \u003ccpu-id\u003e\n type\n mgmtime\n cputime\n onlinetime\n \u003ccpu-id\u003e\n ...\n \u003clpar-name\u003e\n cpus/\n ...\n\n- update: File to trigger update\n- cpus/: Directory for all physical cpus\n- cpus/\u003ccpu-id\u003e/: Directory for one physical cpu.\n- cpus/\u003ccpu-id\u003e/type: Type name of physical zSeries cpu.\n- cpus/\u003ccpu-id\u003e/mgmtime: Physical-LPAR-management time in microseconds.\n- hyp/: Directory for hypervisor information\n- hyp/type: Typ of hypervisor (currently only \u0027LPAR Hypervisor\u0027)\n- systems/: Directory for all LPARs\n- systems/\u003clpar-name\u003e/: Directory for one LPAR.\n- systems/\u003clpar-name\u003e/cpus/\u003ccpu-id\u003e/: Directory for the virtual cpus\n- systems/\u003clpar-name\u003e/cpus/\u003ccpu-id\u003e/type: Typ of cpu.\n- systems/\u003clpar-name\u003e/cpus/\u003ccpu-id\u003e/mgmtime:\nAccumulated number of microseconds during which a physical\nCPU was assigned to the logical cpu and the cpu time was\nconsumed by the hypervisor and was not provided to\nthe LPAR (LPAR overhead).\n\n- systems/\u003clpar-name\u003e/cpus/\u003ccpu-id\u003e/cputime:\nAccumulated number of microseconds during which a physical CPU\nwas assigned to the logical cpu and the cpu time was consumed\nby the LPAR.\n\n- systems/\u003clpar-name\u003e/cpus/\u003ccpu-id\u003e/onlinetime:\nAccumulated number of microseconds during which the logical CPU\nhas been online.\n\nAs mount point for the filesystem /sys/hypervisor/s390 is created.\n\nThe update process is triggered when writing \u0027something\u0027 into the\n\u0027update\u0027 file at the top level hypfs directory. You can do this e.g.\nwith \u0027echo 1 \u003e update\u0027. During the update the whole directory structure\nis deleted and built up again.\n\nCc: Pekka Enberg \u003cpenberg@cs.helsinki.fi\u003e\nCc: Ingo Oeser \u003cioe-lkml@rameria.de\u003e\nCc: Joern Engel \u003cjoern@wohnheim.fh-wedel.de\u003e\nAcked-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nSigned-off-by: Michael Holzheu \u003cholzheu@de.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" } ] }
