When the configuration of\na device is to be changed, first its table is loaded and this structure\nis populated, then the device is \u0027resumed\u0027 and the calculated\nqueue_limits are applied.\n\nThis places restrictions on how userspace may process related devices,\nwhere it is often advantageous to \u0027load\u0027 tables for several devices\nat once before \u0027resuming\u0027 them together. As the new queue_limits\nonly take effect after the \u0027resume\u0027, if they are changing and one\ndevice uses another, the latter must be \u0027resumed\u0027 before the former\nmay be \u0027loaded\u0027.\n\nThis patch moves the calculation of these queue_limits out of\nthe \u0027load\u0027 operation into \u0027resume\u0027. Since we are no longer\npre-calculating this struct, we no longer need to maintain copies\nwithin our dm structs.\n\ndm_set_device_limits() now passes the \u0027start\u0027 of the device\u0027s\ndata area (aka pe_start) as the \u0027offset\u0027 to blk_stack_limits().\n\ninit_valid_queue_limits() is replaced by blk_set_default_limits().\n\nSigned-off-by: Mike Snitzer \u003csnitzer@redhat.com\u003e\nCc: martin.petersen@oracle.com\nSigned-off-by: Alasdair G Kergon \u003cagk@redhat.com\u003e\n" }, { "commit": "18d8594dd93a1ae2fafd591ec026e87d743292bf", "tree": "9a4b0ac8512864666fef0c6e3bc26c5db172f649", "parents": [ "af4874e03ed82f050d5872d8c39ce64bf16b5c38" ], "author": { "name": "Mike Snitzer", "email": "snitzer@redhat.com", "time": "Mon Jun 22 10:12:33 2009 +0100" }, "committer": { "name": "Alasdair G Kergon", "email": "agk@redhat.com", "time": "Mon Jun 22 10:12:33 2009 +0100" }, "message": "dm log: fix create_log_context to use logical_block_size of log device\n\ncreate_log_context() must use the logical_block_size from the log disk,\nwhere the I/O happens, not the target\u0027s logical_block_size.\n\nSigned-off-by: Mike Snitzer \u003csnitzer@redhat.com\u003e\nSigned-off-by: Alasdair G Kergon \u003cagk@redhat.com\u003e\n" }, { "commit": "af4874e03ed82f050d5872d8c39ce64bf16b5c38", "tree": "38aa5dee43b4bb7a369995d4f38dee992cb051e0", "parents": [ "1197764e403d97231eb6da2b1e16f511a7fd3101" ], "author": { "name": "Mike Snitzer", "email": "snitzer@redhat.com", "time": "Mon Jun 22 10:12:33 2009 +0100" }, "committer": { "name": "Alasdair G Kergon", "email": "agk@redhat.com", "time": "Mon Jun 22 10:12:33 2009 +0100" }, "message": "dm target:s introduce iterate devices fn\n\nAdd .iterate_devices to \u0027struct target_type\u0027 to allow a function to be\ncalled for all devices in a DM target.

the\nnormal \"get_user()\" and \"copy_from/to_user()\" accesses, which are done\nthrough the TLB, rather than through the page tables.\n\nWhy? access_ok() does both too few, and too many checks. Too many,\nbecause it is meant for regular kernel accesses that will not honor the\n\u0027user\u0027 bit in the page tables, and because it honors the USER_DS vs\nKERNEL_DS distinction that we shouldn\u0027t care about in GUP. And too few,\nbecause it doesn\u0027t do the \u0027canonical\u0027 check on the address on x86-64,\nsince the TLB will do that for us.\n\nSo instead of using a function that isn\u0027t meant for this, and does\nsomething else and much more complicated, just do the real rules: we\ndon\u0027t want the range to overflow, and on x86-64, we want it to be a\ncanonical low address (on 32-bit, all addresses are canonical).\n\nAcked-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: H.

Once we\nlaunch it a second time, the callsites will never be nopped back,\nunless you set custom filters.\nFor example it happens during the self tests at boot time.\nThe function tracer selftest runs, and then the dynamic tracing is\ntested too. After that, the callsites are left un-nopped.\n\nThis is because the reset callback of the function tracer tries to\nunregister two ftrace callbacks in once: the common function tracer\nand the function tracer with stack backtrace, regardless of which\none is currently in use.\nIt then creates an unbalance on ftrace_start_up value which is expected\nto be zero when the last ftrace callback is unregistered. When it\nreaches zero, the FTRACE_DISABLE_CALLS is set on the next ftrace\ncommand, triggering the patching into nop. But since it becomes\nunbalanced, ie becomes lower than zero, if the kernel functions\nare patched again (as in every further function tracer runs), they\nwon\u0027t ever be nopped back.\n\nNote that ftrace_call and ftrace_graph_call are still patched back\nto ftrace_stub in the off case, but not the callers of ftrace_call\nand ftrace_graph_caller. It means that the tracing is well deactivated\nbut we waste a useless call into every kernel function.\n\nThis patch just unregisters the right ftrace_ops for the function\ntracer on its reset callback and ignores the other one which is\nnot registered, fixing the unbalance. The problem also happens\nis .30\n\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Steven Rostedt \u003crostedt@goodmis.org\u003e\nCc: stable@kernel.org\n" }, { "commit": "0b7af262aba912f52bc6ef76f1bc0960b01b8502", "tree": "887c22e1b4ba59b13501ad3c76471d5f1b25b46d", "parents": [ "a95fe463e73b8c7b2d97606ac86ce261f1270726" ], "author": { "name": "Pierre Willenbrock", "email": "pierre@pirsoft.de", "time": "Fri Jun 19 18:31:47 2009 +0200" }, "committer": { "name": "Dave Airlie", "email": "airlied@redhat.com", "time": "Sat Jun 20 14:16:59 2009 +1000" }, "message": "agp/intel: Make intel_i965_mask_memory use dma_addr_t for physical addresses\n\nOtherwise, the high bits to be stuffed in the unused lower bits of the\npage address are lost.\n\nSigned-off-by: Pierre Willenbrock \u003cpierre@pirsoft.de\u003e\nSigned-off-by: Dave Airlie \u003cairlied@redhat.com\u003e\n" }, { "commit": "fb20871a54961b82d35303b43452928186c1361d", "tree": "1beeb39e45eda1c8b5893090904b583fceeb07ef", "parents": [ "bee89ab228e6f51c4ddd3481b9bd491859a8ee7b", "c7a5d70796379e3d51d0c652fbe1634b81d3bbd5" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Jun 19 17:48:32 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Jun 19 17:48:32 2009 -0700" }, "message": "Merge git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging-2.6\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging-2.6: (342 commits)\n Staging: comedi: fix build errors\n Staging: udlfb: update to version 0.2.3\n Staging: udlfb: fix some sparse warnings.\n Staging: udlfb: clean up checkpatch warnings in udlfb.c\n Staging: udlfb: clean up checkpatch warnings in udlfb.h\n Staging: udlfb: add udlfb driver to build\n Staging: add udlfb driver\n Staging: pata_rdc: remove pointless comments\n Staging: pata_rdc: remove DRIVER macros\n Staging: pata_rdc: remove dbgprintf macro\n Staging: pata_rdc: remove broken flag\n Staging: pata_rdc: fix build warnings\n Staging: pata_rdc: use PCI_DEVICE\n Staging: pata_rdc: remove function prototypes\n Staging: pata_rdc: coding style fixes\n Staging: pata_rdc: convert code to work in 2.6.29\n Staging: pata_rdc: add driver to the build system\n Staging: add pata_rdc driver\n Staging: remove obsolete serqt_usb driver\n Staging: serqt_usb2 add the driver to the build\n ...\n" }, { "commit": "bee89ab228e6f51c4ddd3481b9bd491859a8ee7b", "tree": "1810eef473172ab9e8ff52ded5e81f39eb8af748", "parents": [ "5c6fb0059cec9a3c0f6d88a0ddf3d62ad323cd57", "528da3e9e237059a84a2625e942811cf824a6efd" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Jun 19 17:46:44 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Jun 19 17:46:44 2009 -0700" }, "message": "Merge branch \u0027for-linus\u0027 of git://git.infradead.org/users/eparis/notify\n\n* \u0027for-linus\u0027 of git://git.infradead.org/users/eparis/notify:\n inotify: inotify_destroy_mark_entry could get called twice\n" }, { "commit": "5c6fb0059cec9a3c0f6d88a0ddf3d62ad323cd57", "tree": "49b4ceaeb5686fca4546315155d04633adf25b3c", "parents": [ "31583d6acf940d2951bc8716557b06d9de5a0c4b", "c70366732f67dbdb32f7fe9c6aa59299b76feca6" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Jun 19 17:45:51 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Jun 19 17:45:51 2009 -0700" }, "message": "Merge branch \u0027i2c-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/jdelvare/staging\n\n* \u0027i2c-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/jdelvare/staging:\n i2c: New macro to initialize i2c address lists on the fly\n i2c: Don\u0027t advertise i2c functions when not available\n i2c: Use rwsem instead of mutex for board info\n i2c: Add a sysfs interface to instantiate devices\n i2c: Limit core locking to the necessary sections\n i2c: Kill the redundant client list\n i2c: Kill is_newstyle_driver\n i2c: Merge i2c_attach_client into i2c_new_device\n i2c: Drop i2c_probe function\n i2c: Get rid of the legacy binding model\n i2c: Kill client_register and client_unregister methods\n" } ], "next": "31583d6acf940d2951bc8716557b06d9de5a0c4b" }
