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": "df64d3caab8db6ae17dacd229a03d7689a10c432", "tree": "247fe4f9f39b22186e42e7f4687dd62c2690e47b", "parents": [ "653c42d552d0fd0b05485442aed45dd2d62269c0" ], "author": { "name": "James Bottomley", "email": "James.Bottomley@suse.de", "time": "Tue Jul 27 15:51:13 2010 -0500" }, "committer": { "name": "James Bottomley", "email": "James.Bottomley@suse.de", "time": "Wed Jul 28 09:07:49 2010 -0500" }, "message": "[SCSI] Unify SAM_ and SAM_STAT_ macros\n\nWe have two separate definitions for identical constants with nearly the\nsame name.

This is handled by not resetting rdata-\u003eevent\nton NONE if the rdata is about to be deleted.\n\nHowever, that fix led to the second problem, described by\nBhanu Gollapudi, as follows:\n\u003e Here is the sequence of events. T1 is first LOGO receive thread, T2 is\n\u003e fc_rport_work() scheduled by T1 and T3 is second LOGO receive thread and\n\u003e T4 is fc_rport_work scheduled by T3.\n\u003e\n\u003e 1. (T1)Received 1st LOGO in state Ready\n\u003e 2. (T1)Delete port \u0026 enter to RESTART state.\n\u003e 3. (T1)schdule event_work, since event is RPORT_EV_NONE.\n\u003e 4. (T1)set event \u003d RPORT_EV_LOGO\n\u003e 5. (T1)Enter RESTART state as disc_id is set.\n\u003e 6. (T2)remember to PLOGI, and set event \u003d RPORT_EV_NONE\n\u003e 6. (T3)Received 2nd LOGO\n\u003e 7. (T3)Delete Port \u0026 enter to RESTART state.\n\u003e 8. (T3)schedule event_work, since event is RPORT_EV_NONE.\n\u003e 9. (T3)Enter RESTART state as disc_id is set.\n\u003e 9. (T3)set event \u003d RPORT_EV_LOGO\n\u003e 10.(T2)work restart, enter PLOGI state and issues PLOGI\n\u003e 11.(T4)Since state is not RESTART anymore, restart is not set, and the\n\u003e event is not reset to RPORT_EV_NONE. (current event is RPORT_EV_LOGO).\n\u003e 12. Now, PLOGI succeeds and fc_rport_enter_ready() will not schedule\n\u003e event_work, and hence the rport will never be created, eventually losing\n\u003e the target after dev_loss_tmo.\n\nSo, the problem here is that we were tracking the desire for\nthe rport be restarted by state RESTART, which was otherwise\nequivalent to DELETE. A contributing factor is that we dropped\nthe lock between steps 6 and 10 in thread T2, which allows the\nstate to change, and we didn\u0027t completely re-evaluate then.\n\nThis is hopefully corrected by the following minor redesign:\n\nSimplify the rport restart logic by making the decision to\nrestart after deleting the transport rport. That decision\nis based on a new STARTED flag that indicates fc_rport_login()\nhas been called and fc_rport_logoff() has not been called\nsince then. This replaces the need for the RESTART state.\n\nOnly restart if the rdata is still in DELETED state\nand only if it still has the STARTED flag set.\n\nAlso now, since we clear the event code much later in the\nwork thread, allow for the possibility that the rport may\nhave become READY again via incoming PLOGI, and if so,\nqueue another event to handle that.\n\nIn the problem scenario, the second LOGO received will\ncause the LOGO event to occur again.\n\nReported-by: Bhanu Gollapudi \u003cbprakash@broadcom.com\u003e\nSigned-off-by: Joe Eykholt \u003cjeykholt@cisco.com\u003e\nSigned-off-by: Robert Love \u003crobert.w.love@intel.com\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@suse.de\u003e\n" }, { "commit": "f8fc6c2c99b8085368119d6cf39b997255052826", "tree": "d1ba9ea7fc49fd8c96143cdcf81a8a9892716ee5", "parents": [ "5d4a2e29fba5b2bef95b96a46b338ec4d76fa4fd" ], "author": { "name": "Bhanu Prakash Gollapudi", "email": "bprakash@broadcom.com", "time": "Fri Jun 11 16:44:04 2010 -0700" }, "committer": { "name": "James Bottomley", "email": "James.Bottomley@suse.de", "time": "Tue Jul 27 12:01:46 2010 -0500" }, "message": "[SCSI] libfc: Handle unsolicited PRLO request\n\nResubmitting after incorporating Joe\u0027s review comment.\n\nUnsolicited PRLO request is now handled by sending LS_ACC,\nand then relogin to the remote port if an N-port login\nsession exists for that remote port.\n\nNote that this patch should be applied on top of Joe Eykholt\u0027s\n\"Fix remote port restart problem\" patch.\n\nSigned-off-by: Bhanu Prakash Gollapudi \u003cbprakash@broadcom.com\u003e\nSigned-off-by: Robert Love \u003crobert.w.love@intel.com\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@suse.de\u003e\n" }, { "commit": "5d4a2e29fba5b2bef95b96a46b338ec4d76fa4fd", "tree": "6258349552738e7ff5d1b20eaa20802d41dce9d5", "parents": [ "618461c02b00a658ec8aa07d409cd496a7e254e2" ], "author": { "name": "Joe Eykholt", "email": "jeykholt@cisco.com", "time": "Fri Jun 11 16:43:59 2010 -0700" }, "committer": { "name": "James Bottomley", "email": "James.Bottomley@suse.de", "time": "Tue Jul 27 12:01:46 2010 -0500" }, "message": "[SCSI] fcoe: clean up TBD comments in FCoE prototype header\n\nSome old comments in fc_fcoe.h say TBD long after the\nstandard has been passed by T11.

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.

The new API has the following benefits:\n\n - Generic usage: For kernel internal use and/or device driver.\n - Provide an API for the most use case.\n - Slim API: The whole API provides 25 functions.\n - Linux style habit.\n - DECLARE_KFIFO, DEFINE_KFIFO and INIT_KFIFO Macros\n - Direct copy_to_user from the fifo and copy_from_user into the fifo.\n - The kfifo itself is an in place member of the using data structure, this save an\n indirection access and does not waste the kernel allocator.\n - Lockless access: if only one reader and one writer is active on the fifo,\n which is the common use case, no additional locking is necessary.\n - Remove spinlock - give the user the freedom of choice what kind of locking to use if\n one is required.\n - Ability to handle records. Three type of records are supported:\n - Variable length records between 0-255 bytes, with a record size\n field of 1 bytes.\n - Variable length records between 0-65535 bytes, with a record size\n field of 2 bytes.\n - Fixed size records, which no record size field.\n - Preserve memory resource.\n - Performance!\n - Easy to use!\n\nThis patch:\n\nSince most users want to have the kfifo as part of another object,\nreorganize the code to allow including struct kfifo in another data\nstructure.

One of these things is the possibility for users to call\nosd_end_request, in any condition at any state. This opens up some\nproblems with calling blk_put_request when out-side of the completion\ncallback but calling __blk_put_request when detecting a from-completion\nstate.\n\nThe current hack was working just fine until exofs decided to operate on\nall devices in parallel and wait for the sum of the requests, before\ndeallocating all osd-requests at once. There are two new possible cases\n1. All request in a group are deallocated as part of the last request\u0027s\n async-done, request_queue is locked.\n2. All request in a group where executed asynchronously, but\n de-allocation was delayed to after the async-done, in the context of\n another thread. Async execution but request_queue is not locked.\n\nThe solution I chose was to separate the deallocation of the osd_request\nwhich has the information users need, from the deallocation of the\ninternal(2) requests which impose the locking problem. The internal\nblock-requests are freed unconditionally inside the async-done-callback,\nwhen we know the queue is always locked. If at osd_end_request time we\nstill have a bock-request, then we know it did not come from within an\nasync-done-callback and we can call the regular blk_put_request.\n\nThe internal requests were used for carrying error information after\nexecution. This information is now copied to osd_request members for\nlater analysis by user code.\n\nThe external API and behaviour was unchanged, except now it really\nsupports what was previously advertised.\n\nReported-by: Vineet Agarwal \u003ccheckout.vineet@gmail.com\u003e\nSigned-off-by: Boaz Harrosh \u003cbharrosh@panasas.com\u003e\nCc: Stable Tree \u003cstable@kernel.org\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@suse.de\u003e\n" }, { "commit": "382f51fe2f2276344d8a21447656778cdf6583b6", "tree": "c2836a2cca4126c9c026ce5aa2fdf9f1c8ccded6", "parents": [ "701791cc3c8fc6dd83f6ec8af7e2541b4a316606", "54987386ee3790f3900de4df2ed4deb0e18dfc9f" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Dec 09 19:42:25 2009 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Dec 09 19:42:25 2009 -0800" }, "message": "Merge git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi-misc-2.6\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi-misc-2.6: (222 commits)\n [SCSI] zfcp: Remove flag ZFCP_STATUS_FSFREQ_TMFUNCNOTSUPP\n [SCSI] zfcp: Activate fc4s attributes for zfcp in FC transport class\n [SCSI] zfcp: Block scsi_eh thread for rport state BLOCKED\n [SCSI] zfcp: Update FSF error reporting\n [SCSI] zfcp: Improve ELS ADISC handling\n [SCSI] zfcp: Simplify handling of ct and els requests\n [SCSI] zfcp: Remove ZFCP_DID_MASK\n [SCSI] zfcp: Move WKA port to zfcp FC code\n [SCSI] zfcp: Use common code definitions for FC CT structs\n [SCSI] zfcp: Use common code definitions for FC ELS structs\n [SCSI] zfcp: Update FCP protocol related code\n [SCSI] zfcp: Dont fail SCSI commands when transitioning to blocked fc_rport\n [SCSI] zfcp: Assign scheduled work to driver queue\n [SCSI] zfcp: Remove STATUS_COMMON_REMOVE flag as it is not required anymore\n [SCSI] zfcp: Implement module unloading\n [SCSI] zfcp: Merge trace code for fsf requests in one function\n [SCSI] zfcp: Access ports and units with container_of in sysfs code\n [SCSI] zfcp: Remove suspend callback\n [SCSI] zfcp: Remove global config_mutex\n [SCSI] zfcp: Replace local reference counting with common kref\n ...\n" }, { "commit": "0a55256d158c18e4821c248a295b7f8f4423660f", "tree": "c1edd634a07cbe980bbf5dbf1f657d386a6a049d", "parents": [ "63e27fb80c2010678681cef7b528ab8af3624fe9" ], "author": { "name": "Christof Schmitt", "email": "christof.schmitt@de.ibm.com", "time": "Tue Nov 24 16:53:57 2009 +0100" }, "committer": { "name": "James Bottomley", "email": "James.Bottomley@suse.de", "time": "Fri Dec 04 12:02:00 2009 -0600" }, "message": "[SCSI] libfc: Add target reset flag to FCP header file\n\nWhile the target reset task management function has been deprecated in\nnewer specs, it is still in use by SCSI FC drivers and there is no\nreal replacement.
