The discard bio is locked in a dm_bio_prison_cell in process_discard\n to lock out parallel activity against the same block.\n\n4. The non-discard bio\u0027s mapping continues and its all_io_entry is\n incremented so the bio is accounted for in the thin pool\u0027s all_io_ds\n which is a dm_deferred_set used to track time locality of non-discard IO.\n\n5. The non-discard bio is finally locked in a dm_bio_prison_cell in\n process_bio.\n\nThe race can result in deadlock, leaving the block layer hanging waiting\nfor completion of a discard bio that never completes, e.g.:\n\nINFO: task ruby:15354 blocked for more than 120 seconds.\n\"echo 0 \u003e /proc/sys/kernel/hung_task_timeout_secs\" disables this message.\nruby D ffffffff8160f0e0 0 15354 15314 0x00000000\n ffff8802fb08bc58 0000000000000082 ffff8802fb08bfd8 0000000000012900\n ffff8802fb08a010 0000000000012900 0000000000012900 0000000000012900\n ffff8802fb08bfd8 0000000000012900 ffff8803324b9480 ffff88032c6f14c0\nCall Trace:\n [\u003cffffffff814e5a19\u003e] schedule+0x29/0x70\n [\u003cffffffff814e3d85\u003e] schedule_timeout+0x195/0x220\n [\u003cffffffffa06b9bc1\u003e] ? _dm_request+0x111/0x160 [dm_mod]\n [\u003cffffffff814e589e\u003e] wait_for_common+0x11e/0x190\n [\u003cffffffff8107a170\u003e] ? try_to_wake_up+0x2b0/0x2b0\n [\u003cffffffff814e59ed\u003e] wait_for_completion+0x1d/0x20\n [\u003cffffffff81233289\u003e] blkdev_issue_discard+0x219/0x260\n [\u003cffffffff81233e79\u003e] blkdev_ioctl+0x6e9/0x7b0\n [\u003cffffffff8119a65c\u003e] block_ioctl+0x3c/0x40\n [\u003cffffffff8117539c\u003e] do_vfs_ioctl+0x8c/0x340\n [\u003cffffffff8119a547\u003e] ? block_llseek+0x67/0xb0\n [\u003cffffffff811756f1\u003e] sys_ioctl+0xa1/0xb0\n [\u003cffffffff810561f6\u003e] ? sys_rt_sigprocmask+0x86/0xd0\n [\u003cffffffff814ef099\u003e] system_call_fastpath+0x16/0x1b\n\nThe thinp-test-suite\u0027s test_discard_random_sectors reliably hits this\ndeadlock on fast SSD storage.\n\nThe fix for this race is that the all_io_entry for a bio must be\nincremented whilst the dm_bio_prison_cell is held for the bio\u0027s\nassociated virtual and physical blocks. That cell locking wasn\u0027t\noccurring early enough in thin_bio_map. This patch fixes this.\n\nCare is taken to always call the new function inc_all_io_entry() with\nthe relevant cells locked, but they are generally unlocked before\ncalling issue() to try to avoid holding the cells locked across\ngeneric_submit_request.\n\nAlso, now that thin_bio_map may lock bios in a cell, process_bio() is no\nlonger the only thread that will do so. Because of this we must be sure\nto use cell_defer_except() to release all non-holder entries, that\nwere added by the other thread, because they must be deferred.\n\nThis patch depends on \"dm thin: replace dm_cell_release_singleton with\ncell_defer_except\".\n\nSigned-off-by: Joe Thornber \u003cejt@redhat.com\u003e\nSigned-off-by: Mike Snitzer \u003csnitzer@redhat.com\u003e\nSigned-off-by: Alasdair G Kergon \u003cagk@redhat.com\u003e\nCc: stable@vger.kernel.org\n" }, { "commit": "b7ca9c9273e5eebd63880dd8a6e4e5c18fc7901d", "tree": "8022d8d5f6f03d80896407562b48c554a8cbfa6f", "parents": [ "c1a94672a830e01d58c7c7e8de530c3f136d6ff2" ], "author": { "name": "Joe Thornber", "email": "ejt@redhat.com", "time": "Fri Dec 21 20:23:31 2012 +0000" }, "committer": { "name": "Alasdair G Kergon", "email": "agk@redhat.com", "time": "Fri Dec 21 20:23:31 2012 +0000" }, "message": "dm thin: replace dm_cell_release_singleton with cell_defer_except\n\nChange existing users of the function dm_cell_release_singleton to share\ncell_defer_except instead, and then remove the now-unused function.\n\nEverywhere that calls dm_cell_release_singleton, the bio in question\nis the holder of the cell.\n\nIf there are no non-holder entries in the cell then cell_defer_except\nbehaves exactly like dm_cell_release_singleton.

The processing of this patch is as follows.\n\n Step 1) Attempt to get the watchdog base address from indirect I/O (0xCD6\n and 0xCD7).\n - Go to the step 7 if obtained address hasn\u0027t conflicted with other\n resource. But, currently, the address (0xfec000f0) conflicts with the\n IOAPIC MMIO address, and the following message is logged.\n\n SP5100 TCO timer: mmio address 0xfec000f0 already in use\n\n 0xfec000f0 is recommended by AMD BIOS Developer\u0027s Guide. So, go to the\n next step.\n\n Step 2) Attempt to get the SBResource_MMIO base address from AcpiMmioEN (for\n SB8x0, PM_Reg:24h) or SBResource_MMIO (SP5100/SB7x0, PCI_Reg:9Ch)\n register.\n - Go to the step 7 if these register has enabled by BIOS, and obtained\n address hasn\u0027t conflicted with other resource.\n - If above condition isn\u0027t true, go to the next step.\n\n Step 3) Attempt to get the free MMIO address from allocate_resource().\n - Go to the step 7 if these register has enabled by BIOS, and obtained\n address hasn\u0027t conflicted with other resource.\n - Driver initialization has failed if obtained address has conflicted\n with other resource, and no \u0027force_addr\u0027 parameter is specified.\n\n Step 4) Use the specified address If \u0027force_addr\u0027 parameter is specified.\n - allocate_resource() function may fail, when the PCI bridge device occupies\n iomem resource from 0xf0000000 to 0xffffffff. To handle such a case,\n I added \u0027force_addr\u0027 parameter to sp5100_tco driver. With \u0027force_addr\u0027\n parameter, sp5100_tco driver directly can assign MMIO address for watchdog\n timer from free iomem region. Note that It\u0027s dangerous to specify wrong\n address in the \u0027force_addr\u0027 parameter.\n\n Example of force_addr parameter use\n # cat /proc/iomem\n ...snip...\n fec00000-fec003ff : IOAPIC 0\n \u003c--- free MMIO region\n fec10000-fec1001f : pnp 00:0b\n fec20000-fec203ff : IOAPIC 1\n ...snip...\n # cat /etc/modprobe.d/sp5100_tco.conf\n options sp5100_tco force_addr\u003d0xfec00800\n # modprobe sp5100_tco\n # cat /proc/iomem\n ...snip...\n fec00000-fec003ff : IOAPIC 0\n fec00800-fec00807 : SP5100 TCO \u003c--- watchdog timer MMIO address\n fec10000-fec1001f : pnp 00:0b\n fec20000-fec203ff : IOAPIC 1\n ...snip...\n #\n\n - Driver initialization has failed if specified address has conflicted\n with other resource.\n\n Step 5) Disable the watchdog timer\n - To rewrite the watchdog timer register of the chipset, absolutely\n guarantee that the watchdog timer is disabled.\n\n Step 6) Re-program the watchdog timer MMIO address to chipset.\n - Re-program the obtained MMIO address in Step 3 or Step 4 to chipset via\n indirect I/O (0xCD6 and 0xCD7).\n\n Step 7) Enable and setup the watchdog timer\n\nThis patch has worked fine on my test environment (ASUS M4A89GTD-PRO/USB3 and\nDL165G7). therefore I believe that it\u0027s no problem to re-program the MMIO\naddress for watchdog timer to chipset during disabled watchdog. However,\nI\u0027m not sure about it, because I don\u0027t know much about chipset programming.\n\nSo, any comments will be welcome.\n\nBugzilla: https://bugzilla.kernel.org/show_bug.cgi?id\u003d43176\nTested-by: Arkadiusz Miskiewicz \u003carekm@maven.pl\u003e\nTested-by: Paul Menzel \u003cpaulepanter@users.sourceforge.net\u003e\nSigned-off-by: Takahisa Tanaka \u003cmc74hc00@gmail.com\u003e\nSigned-off-by: Wim Van Sebroeck \u003cwim@iguana.be\u003e\n" }, { "commit": "902e2e7d482c55395652ff78cb3457fc390b101d", "tree": "75b1540807e49526821eb058ad642338754b0c47", "parents": [ "0360dffedd7bad92f174b2ce5e69e960451d2b59" ], "author": { "name": "Murali Karicheri", "email": "m-karicheri2@ti.com", "time": "Mon Nov 26 16:41:35 2012 -0500" }, "committer": { "name": "Wim Van Sebroeck", "email": "wim@iguana.be", "time": "Wed Dec 19 22:25:08 2012 +0100" }, "message": "watchdog: davinci_wdt: add OF support\n\nThis adds OF support for davinci_wdt driver.\n\nSigned-off-by: Murali Karicheri \u003cm-karicheri2@ti.com\u003e\nAcked-by: Grant Likely \u003cgrant.likely@secretlab.ca\u003e\nSigned-off-by: Wim Van Sebroeck \u003cwim@iguana.be\u003e\n" }, { "commit": "0360dffedd7bad92f174b2ce5e69e960451d2b59", "tree": "413b8a3c5d96867ed288b7040bca5e8f600fd3bb", "parents": [ "2bc3f62f9627f136bb52b4cfa43060ef04656d2f" ], "author": { "name": "Tushar Behera", "email": "tushar.behera@linaro.org", "time": "Thu Nov 22 10:13:04 2012 +0530" }, "committer": { "name": "Wim Van Sebroeck", "email": "wim@iguana.be", "time": "Wed Dec 19 22:25:07 2012 +0100" }, "message": "watchdog: da9052: Fix invalid free of devm_ allocated data\n\nIt is not required to free devm_ allocated data.
