A volatile autocluster is a cluster of related controls where one\ncontrol is the control that toggles between manual and auto mode and the other\ncontrols are the values for the manual mode. For example autogain and gain,\nautoexposure and exposure, etc.\n\nIf the hardware lets you read out the automatically calculated manual values\nwhile in automode, then those manual controls should be marked volatile.\n\ngain value as calculated by the autogain circuitry, then you would mark the\ngain control as volatile (i.e. continuously changing).\n\nThe question in such use cases is what to do when switching from the auto\nmode to the manual mode. Should we switch to the last set manual values or\nshould the volatile values be copied and used as the initial manual values.\n\nFor example: suppose the mode is manual gain and gain is set to 5. Then\nautogain is turned on and the gain is set by the hardware to 2. Finally\nthe user switches back to manual gain. What should the gain be? 2 or 5?\n\nAfter a long discussion the decisions was made to keep the last value as\ncalculated by the auto mode (so 2 in the example above).\n\nThe reason is that webcams that do such things will adapt themselves to\nthe current light conditions and when you switch back to manual mode you\nexpect that you keep the same picture. If you would switch back to old\nmanual values, then that would give you a suddenly different picture,\nwhich is jarring for the user.\n\nAdditionally, this would be difficult to implement in applications that\nstore and restore the control values at application exit and start.\n\nIf you want to keep the old manual values when you switch from auto to\nmanual, then there would have to be a way for applications to get hold\nof those old values while in auto mode, but there isn\u0027t.\n\nSo this patch will do all the heavy lifting in v4l2-ctrls.c: if you go\nfrom auto mode to manual mode and the manual controls are volatile, then\ng_volatile_ctrl will be called to get the current values for the manual\ncontrols before switching to manual mode.\n\nSigned-off-by: Hans Verkuil \u003chans.verkuil@cisco.com\u003e\nAcked-by: Hans de Goede \u003chdegoede@redhat.com\u003e\nSigned-off-by: Mauro Carvalho Chehab \u003cmchehab@redhat.com\u003e\n" }, { "commit": "88365105d683187e02a4f75220eaf51fd0c0b6e0", "tree": "acbc18b9e8eb7f74630fb7fd709cb35eafd30f54", "parents": [ "74a45790861f659058e8f8b565d98e5a1fdd8440" ], "author": { "name": "Hans Verkuil", "email": "hans.verkuil@cisco.com", "time": "Fri Aug 26 07:35:14 2011 -0300" }, "committer": { "name": "Mauro Carvalho Chehab", "email": "mchehab@redhat.com", "time": "Wed Sep 21 09:52:21 2011 -0300" }, "message": "[media] v4l2-ctrls: replace is_volatile with V4L2_CTRL_FLAG_VOLATILE\n\nWith the new flag there is no need anymore to have a separate is_volatile\nfield.

introduced a performance regression when\nrunning any sort of fsyncing workload using dm-multipath and certain\nstorage (in our case, an HP EVA). The test I ran was fs_mark, and it\ndropped from ~800 files/sec on ext4 to ~100 files/sec. It turns out\nthat dm-multipath always advertised flush+fua support, and passed\ncommands on down the stack, where those flags used to get stripped off.\nThe above commit changed that behavior:\n\nstatic inline struct request *__elv_next_request(struct request_queue *q)\n{\n struct request *rq;\n\n while (1) {\n- while (!list_empty(\u0026q-\u003equeue_head)) {\n+ if (!list_empty(\u0026q-\u003equeue_head)) {\n rq \u003d list_entry_rq(q-\u003equeue_head.next);\n- if (!(rq-\u003ecmd_flags \u0026 (REQ_FLUSH | REQ_FUA)) ||\n- (rq-\u003ecmd_flags \u0026 REQ_FLUSH_SEQ))\n- return rq;\n- rq \u003d blk_do_flush(q, rq);\n- if (rq)\n- return rq;\n+ return rq;\n }\n\nNote that previously, a command would come in here, have\nREQ_FLUSH|REQ_FUA set, and then get handed off to blk_do_flush:\n\nstruct request *blk_do_flush(struct request_queue *q, struct request *rq)\n{\n unsigned int fflags \u003d q-\u003eflush_flags; /* may change, cache it */\n bool has_flush \u003d fflags \u0026 REQ_FLUSH, has_fua \u003d fflags \u0026 REQ_FUA;\n bool do_preflush \u003d has_flush \u0026\u0026 (rq-\u003ecmd_flags \u0026 REQ_FLUSH);\n bool do_postflush \u003d has_flush \u0026\u0026 !has_fua \u0026\u0026 (rq-\u003ecmd_flags \u0026\n REQ_FUA);\n unsigned skip \u003d 0;\n...\n if (blk_rq_sectors(rq) \u0026\u0026 !do_preflush \u0026\u0026 !do_postflush) {\n rq-\u003ecmd_flags \u0026\u003d ~REQ_FLUSH;\n\t\tif (!has_fua)\n\t\t\trq-\u003ecmd_flags \u0026\u003d ~REQ_FUA;\n\t return rq;\n\t}\n\nSo, the flush machinery was bypassed in such cases (q-\u003eflush_flags \u003d\u003d 0\n\u0026\u0026 rq-\u003ecmd_flags \u0026 (REQ_FLUSH|REQ_FUA)).\n\nNow, however, we don\u0027t get into the flush machinery at all. Instead,\n__elv_next_request just hands a request with flush and fua bits set to\nthe scsi_request_fn, even if the underlying request_queue does not\nsupport flush or fua.\n\nThe agreed upon approach is to fix the flush machinery to allow\nstacking. While this isn\u0027t used in practice (since there is only one\nrequest-based dm target, and that target will now reflect the flush\nflags of the underlying device), it does future-proof the solution, and\nmake it function as designed.\n\nIn order to make this work, I had to add a field to the struct request,\ninside the flush structure (to store the original req-\u003eend_io). Shaohua\nhad suggested overloading the union with rb_node and completion_data,\nbut the completion data is used by device mapper and can also be used by\nother drivers. So, I didn\u0027t see a way around the additional field.\n\nI tested this patch on an HP EVA with both ext4 and xfs, and it recovers\nthe lost performance. Comments and other testers, as always, are\nappreciated.\n\nCheers,\nJeff\n\nSigned-off-by: Jeff Moyer \u003cjmoyer@redhat.com\u003e\nAcked-by: Tejun Heo \u003ctj@kernel.org\u003e\nSigned-off-by: Jens Axboe \u003cjaxboe@fusionio.com\u003e\n" }, { "commit": "97c24d1d455df17ca3ef281d1a290988f4686643", "tree": "36e4602be13301bf1669fcb7998b8a2d431cf1c9", "parents": [ "91d85ea6786107aa2837bef3e957165ad7c8b823", "7fd781e8f9b72544a1c7f04456eb33d5ffaed592" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sun Aug 14 12:28:15 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sun Aug 14 12:28:15 2011 -0700" }, "message": "Merge branch \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/cjb/mmc\n\n* \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/cjb/mmc:\n mmc: remove unused \"ddr\" parameter in struct mmc_ios\n mmc: dw_mmc: Fix DDR mode support.\n mmc: core: use defined R1_STATE_PRG macro for card status\n mmc: sdhci: use f_max instead of host-\u003eclock for timeouts\n mmc: sdhci: move timeout_clk calculation farther down\n mmc: sdhci: check host-\u003eclock before using it as a denominator\n mmc: Revert \"mmc: sdhci: Fix SDHCI_QUIRK_TIMEOUT_USES_SDCLK\"\n mmc: tmio: eliminate unused variable \u0027mmc\u0027 warning\n mmc: esdhc-imx: fix card interrupt loss on freescale eSDHC\n mmc: sdhci-s3c: Fix build for header change\n mmc: dw_mmc: Fix mask in IDMAC_SET_BUFFER1_SIZE macro\n mmc: cb710: fix possible pci_dev leak in cb710_pci_configure()\n mmc: core: Detect eMMC v4.5 ext_csd entries\n mmc: mmc_test: avoid stalled file in debugfs\n mmc: sdhci-s3c: add BROKEN_ADMA_ZEROLEN_DESC quirk\n mmc: sdhci: pxav3: controller needs 32 bit ADMA addressing\n mmc: sdhci: fix retuning timer wrongly deleted in sdhci_tasklet_finish\n" }, { "commit": "17f2ae7f677f023997e02fd2ebabd90ea2a0390d", "tree": "9f333057d8771adc432687417c2bfe28164f1e48", "parents": [ "91d85ea6786107aa2837bef3e957165ad7c8b823" ], "author": { "name": "Rafael J.

exceeding via setuid() and\nsimilar functions.\n\nBefore the check there was a possibility to greatly exceed the allowed\nnumber of processes by an unprivileged user if the program relied on\nrlimit only. But the check created new security threat: many poorly\nwritten programs simply don\u0027t check setuid() return code and believe it\ncannot fail if executed with root privileges. So, the check is removed\nin this patch because of too often privilege escalations related to\nbuggy programs.\n\nThe NPROC can still be enforced in the common code flow of daemons\nspawning user processes. Most of daemons do fork()+setuid()+execve().\nThe check introduced in execve() (1) enforces the same limit as in\nsetuid() and (2) doesn\u0027t create similar security issues.\n\nNeil Brown suggested to track what specific process has exceeded the\nlimit by setting PF_NPROC_EXCEEDED process flag. With the change only\nthis process would fail on execve(), and other processes\u0027 execve()\nbehaviour is not changed.\n\nSolar Designer suggested to re-check whether NPROC limit is still\nexceeded at the moment of execve(). If the process was sleeping for\ndays between set*uid() and execve(), and the NPROC counter step down\nunder the limit, the defered execve() failure because NPROC limit was\nexceeded days ago would be unexpected.

Scanning in place doubles the speed, so it\u0027s now only\ntwice as slow as before (or three times slower when the PROVEs are on).\n\nSo, add radix_tree_locate_item() as an expedient, once-off,\nsingle-caller hack to do the lookup directly in place. #ifdef it on\nCONFIG_SHMEM and CONFIG_SWAP, as much to document its limited\napplicability as save space in other configurations. And, sadly,\n#include sched.h for cond_resched().\n\nSigned-off-by: Hugh Dickins \u003chughd@google.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "69f07ec938712b58755add82dd3d0b35f01317cc", "tree": "7a0a704ed4bc79dbba50454093469d0ce31ef1a4", "parents": [ "6922c0c7abd387374255801f7739624867e8acad" ], "author": { "name": "Hugh Dickins", "email": "hughd@google.com", "time": "Wed Aug 03 16:21:26 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Aug 03 14:25:24 2011 -1000" }, "message": "tmpfs: use kmemdup for short symlinks\n\nBut we\u0027ve not yet removed the old swp_entry_t i_direct[16] from\nshmem_inode_info.
