get a .llseek operation so we can make\nnonseekable_open the default for future file operations without a\n.llseek pointer.\n\nThe three cases that we can automatically detect are no_llseek, seq_lseek\nand default_llseek. 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. Existing drivers can be converted\nto do the same when the maintainer knows for certain that no user code\nrelies on calling seek on the device file.\n\nThe generated code is often incorrectly indented and right now contains\ncomments that clarify for each added line why a specific variant was\nchosen. 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

Only\nthe machanism is provided; use of it is up to the various high-level\ndrivers, and the patch doesn\u0027t change any of them. Except for sg --\nthe patch expicitly prevents a device from being runtime-suspended\nwhile its sg device file is open.\n\nThe implementation is simplistic. In general, hosts and targets are\nautomatically suspended when all their children are asleep, but for\nthem the runtime-suspend code doesn\u0027t actually do anything. (A host\u0027s\nruntime PM status is propagated up the device tree, though, so a\nruntime-PM-aware lower-level driver could power down the host adapter\nhardware at the appropriate times.) There are comments indicating\nwhere a transport class might be notified or some other hooks added.\n\nLUNs are runtime-suspended by calling the drivers\u0027 existing suspend\nhandlers (and likewise for runtime-resume). Somewhat arbitrarily, the\nimplementation delays for 100 ms before suspending an eligible LUN.\nThis is because there typically are occasions during bootup when the\nsame device file is opened and closed several times in quick\nsuccession.\n\nThe way this all works is that the SCSI core increments a device\u0027s\nPM-usage count when it is registered. If a high-level driver does\nnothing then the device will not be eligible for runtime-suspend\nbecause of the elevated usage count. If a high-level driver wants to\nuse runtime PM then it can call scsi_autopm_put_device() in its probe\nroutine to decrement the usage count and scsi_autopm_get_device() in\nits remove routine to restore the original count.\n\nHosts, targets, and LUNs are not suspended while they are being probed\nor removed, or while the error handler is running. In fact, a fairly\nlarge part of the patch consists of code to make sure that things\naren\u0027t suspended at such times.\n\n[jejb: fix up compile issues in PM config variations]\nSigned-off-by: Alan Stern \u003cstern@rowland.harvard.edu\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@suse.de\u003e\n" }, { "commit": "caf19d38607108304cd8cc67ed21378017f69e8a", "tree": "ae2730729cb88b30bdd90f692b18866dc8485b7a", "parents": [ "240778e821f596a6954116107c5cc3456df84f81" ], "author": { "name": "FUJITA Tomonori", "email": "fujita.tomonori@lab.ntt.co.jp", "time": "Thu Jul 22 09:36:51 2010 +0900" }, "committer": { "name": "James Bottomley", "email": "James.Bottomley@suse.de", "time": "Wed Jul 28 09:06:05 2010 -0500" }, "message": "[SCSI] sg: fix bio leak with a detached device\n\nAfter blk_rq_map_user is successful, if we find that a device is\nunavailable (was detached), we must call blk_end_request_all to free\nbio(s) before blk_rq_unmap_user and blk_put_request.\n\nReported-by: \"Dailey, Nate\" \u003cNate.Dailey@stratus.com\u003e\nSigned-off-by: FUJITA Tomonori \u003cfujita.tomonori@lab.ntt.co.jp\u003e\nTested-by: \"Dailey, Nate\" \u003cNate.Dailey@stratus.com\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@suse.de\u003e\n" }, { "commit": "f4927c45beda9a70e5c3bda0bd9f12b4f713c00b", "tree": "18256d3dd635e931838e3d83b071ca5a1e61a163", "parents": [ "16ef8def80ea97c3cacdcaa765bdf62b2d94f86d" ], "author": { "name": "Arnd Bergmann", "email": "arnd@arndb.de", "time": "Tue Apr 27 00:24:01 2010 +0200" }, "committer": { "name": "Frederic Weisbecker", "email": "fweisbec@gmail.com", "time": "Mon May 17 05:27:04 2010 +0200" }, "message": "scsi: Push down BKL into ioctl functions\n\nPush down the bkl into ioctl functions on the scsi layer.\n\n[jkacur: Forward declaration missing \u0027;\u0027.\nConflicting declaraction in megaraid.h changed\nFixed missing inodes declarations]\n\nSigned-off-by: Arnd Bergmann \u003carnd@arndb.de\u003e\nSigned-off-by: John Kacur \u003cjkacur@redhat.com\u003e\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\n" }, { "commit": "5a0e3ad6af8660be21ca98a971cd00f331318c05", "tree": "5bfb7be11a03176a87296a43ac6647975c00a1d1", "parents": [ "ed391f4ebf8f701d3566423ce8f17e614cde9806" ], "author": { "name": "Tejun Heo", "email": "tj@kernel.org", "time": "Wed Mar 24 17:04:11 2010 +0900" }, "committer": { "name": "Tejun Heo", "email": "tj@kernel.org", "time": "Tue Mar 30 22:02:32 2010 +0900" }, "message": "include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h\n\npercpu.h is included by sched.h and module.h and thus ends up being\nincluded when building most .c files. percpu.h includes slab.h which\nin turn includes gfp.h making everything defined by the two files\nuniversally available and complicating inclusion dependencies.\n\npercpu.h -\u003e slab.h dependency is about to be removed. 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.

This would overwrite\n some or all of the kernel buffer\n - copy kernel (LLD) buffer back to the user space.\n\nThe idea was to detect short reads by filling the original\nuser space buffer with some marker bytes (\"0xec\" it would\nseem in this report). The \"resid\" value is a better way\nof detecting short reads but that was only added this century\nand requires co-operation from the LLD.\n\u003d\n\nThis patch changes the block layer mapping API to support this\nsemantics. This simply adds another field to struct rq_map_data and\nenables __bio_copy_iov() to copy data from user space even with READ\nrequests.\n\nIt\u0027s better to add the flags field and kills null_mapped and the new\nfrom_user fields in struct rq_map_data but that approach makes it\ndifficult to send this patch to stable trees because st and osst\ndrivers use struct rq_map_data (they were converted to use the block\nlayer in 2.6.29 and 2.6.30).

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.
