It removes all interpretation and visualization parts\nand focuses on bare logging of the information.\n\nThis patch deals with all trace records of the zfcp error recovery.\n\nSigned-off-by: Swen schillig \u003cswen@vnet.ibm.com\u003e\nSigned-off-by: Christof Schmitt \u003cchristof.schmitt@de.ibm.com\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@suse.de\u003e\n" }, { "commit": "e55f87531c2c1eb071a296df7eb67f83d5f0b5df", "tree": "eabe0f87e2ddb4ca2641ee4fe6a136dc7cbe04de", "parents": [ "14718e3cd8e9c6937114cebbf3ce5d504328da8c" ], "author": { "name": "Christof Schmitt", "email": "christof.schmitt@de.ibm.com", "time": "Thu Nov 18 14:53:18 2010 +0100" }, "committer": { "name": "James Bottomley", "email": "James.Bottomley@suse.de", "time": "Thu Dec 09 09:41:23 2010 -0600" }, "message": "[SCSI] zfcp: Issue FCP command without holding SCSI host_lock\n\nInterrupting the connection to the FCP channel while I/O requests are\nbeing issued can lead to this deadlock. scsi_dispatch_cmd already\nholds the host_lock while the recovery trigger tries to acquire the\nhost_lock again when iterating through the scsi_devices.\n\n INFO: lockdep is turned off.\n BUG: spinlock lockup on CPU#1, blast/9660, 0000000078f38878\n CPU: 1 Not tainted 2.6.35.7SWEN2 #2\n Process blast (pid: 9660, task: 0000000071f75940, ksp: 0000000074393ac0)\n 0000000074393640 00000000743935c0 0000000000000002 0000000000000000\n 0000000074393660 00000000743935d8 00000000743935d8 00000000005590c2\n 0000000000000000 0000000078f38878 0000000026ede800 0000000078f38878\n 000000000000000d 040000000000000c 0000000074393628 0000000000000000\n 0000000000000000 0000000000100b2a 00000000743935c0 0000000074393600\n Call Trace:\n ([\u003c0000000000100a32\u003e] show_trace+0xee/0x144)\n [\u003c00000000003be202\u003e] do_raw_spin_lock+0x112/0x178\n [\u003c000000000055d408\u003e] _raw_spin_lock_irqsave+0x90/0xb0\n [\u003c00000000003f1514\u003e] __scsi_iterate_devices+0x38/0xbc\n [\u003c00000000004849b0\u003e] zfcp_erp_clear_adapter_status+0xd0/0x16c\n [\u003c000000000048587a\u003e] zfcp_erp_adapter_reopen+0x3a/0xb4\n [\u003c0000000000489812\u003e] zfcp_fsf_req_send+0x166/0x180\n [\u003c000000000048c8d6\u003e] zfcp_fsf_fcp_cmnd+0x272/0x408\n [\u003c000000000048f864\u003e] zfcp_scsi_queuecommand+0x11c/0x1e0\n [\u003c00000000003f1f2a\u003e] scsi_dispatch_cmd+0x1d6/0x324\n [\u003c00000000003f9910\u003e] scsi_request_fn+0x42c/0x56c\n [\u003c00000000003828ae\u003e] __blk_run_queue+0x86/0x140\n [\u003c000000000037f742\u003e] elv_insert+0x11a/0x208\n [\u003c000000000038104c\u003e] blk_insert_cloned_request+0x84/0xe4\n [\u003c000003c0032b7c64\u003e] dm_dispatch_request+0x6c/0x94 [dm_mod]\n [\u003c000003c0032b7d5c\u003e] map_request+0xd0/0x100 [dm_mod]\n [\u003c000003c0032b9a78\u003e] dm_request_fn+0xec/0x1bc [dm_mod]\n [\u003c0000000000382c0e\u003e] generic_unplug_device+0x5a/0x6c\n [\u003c000003c0032b7f98\u003e] dm_unplug_all+0x74/0x9c [dm_mod]\n [\u003c00000000001d1272\u003e] sync_page+0x76/0x9c\n [\u003c00000000001d12ba\u003e] sync_page_killable+0x22/0x60\n [\u003c000000000055a768\u003e] __wait_on_bit_lock+0xc0/0x124\n [\u003c00000000001d1140\u003e] __lock_page_killable+0x78/0x84\n [\u003c00000000001d351c\u003e] generic_file_aio_read+0x5a4/0x7e8\n [\u003c0000000000228ec0\u003e] do_sync_read+0xc8/0x12c\n [\u003c0000000000229edc\u003e] vfs_read+0xac/0x1ac\n [\u003c000000000022a0d8\u003e] SyS_read+0x58/0xa8\n [\u003c00000000001146de\u003e] sysc_noemu+0x10/0x16\n [\u003c00000200000493c4\u003e] 0x200000493c4\n INFO: lockdep is turned off.\n\nCall zfcp_fsf_fcp_cmnd without the host_lock and disable the\ninterrupts when acquiring the req_q_lock.

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 new code is currently sitting in linux-next that should get\nthe same modifications, which I will do at the end of the merge window.\n\nMany thanks to Julia Lawall for helping me learn to write a

If the upper-layer driver wants to\nstop polling it calls qdio_start_irq().\n\nSince adapter interrupts are not completely stoppable qdio implements\na software bit QDIO_QUEUE_IRQS_DISABLED to safely disable interrupts for an\ninput queue.\n\nThe old interface is preserved and will be used as is by zfcp.\n\nSigned-off-by: Jan Glauber \u003cjang@linux.vnet.ibm.com\u003e\nSigned-off-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nSigned-off-by: Frank Blaschka \u003cfrank.blaschka@de.ibm.com\u003e\nSigned-off-by: David S.

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. Build test were done on the following configurations and failures\n were fixed.
