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.

Modifies fc_exch_mgr_alloc to accept EM match function and then\n have allocated EM added to the lport using fc_exch_mgr_add API\n while also updating EM kref for newly added EM.\n\n 2. Updates fc_exch_mgr_free API to accept only lport pointer instead\n EM and then have this API free all EMs of the lport from EM anchor\n list.\n\n 3. Removes single lport pointer link from the EM, which was used in\n associating lport pointer in newly allocated exchange. Instead have\n lport pointer passed along new exchange allocation call path and\n then store passed lport pointer in newly allocated exchange, this\n will allow a single EM instance to be used across more than one\n lport and used in EM reset to reset only lport specific exchanges.\n\n 4. Modifies fc_exch_mgr_reset to reset all EMs from the EM anchor list\n of the lport, adds additional exch lport pointer (ep-\u003elp) check for\n shared EM case to reset exchange specific to a lport requested reset.\n\n 5. Updates exch allocation API fc_exch_alloc to use EM anchor list and\n its anchor match func pointer. The fc_exch_alloc will walk the list\n of EMs until it finds a match, a match will be either null match\n func pointer or call to match function returning true value.\n\n 6. Updates fc_exch_recv to accept incoming frame on local port using\n only lport pointer and frame pointer without specifying EM instance\n of incoming frame. Instead modified fc_exch_recv to locate EM for the\n incoming frame by matching xid of incoming frame against a EM xid range.\n This change was required to use EM list in libfc Rx path and after this\n change the lport fc_exch_mgr pointer emp is not needed anymore, so\n removed emp pointer.\n\n 7. Updates fnic for removed lport emp pointer and above modified libfc APIs\n fc_exch_recv, fc_exch_mgr_alloc and fc_exch_mgr_free.\n\n 8. Removes exch_get and exch_put from libfc_function_template as these\n are no longer needed with EM anchor list and its match function use.\n Also removes its default function fc_exch_get.\n\nA defect this patch introduced regarding the libfc initialization order in\nthe fnic driver was fixed by Joe Eykholt \u003cjeykholt@cisco.com\u003e.\n\nSigned-off-by: Vasu Dev \u003cvasu.dev@intel.com\u003e\nSigned-off-by: Robert Love \u003crobert.w.love@intel.com\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@HansenPartnership.com\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@suse.de\u003e\n" } ], "next": "d459b7ea1b4c7aa3dacfeee174d02b2f7a95850d" }
