This means that when\nthe endio threads aren\u0027t running, the rest of the FS isn\u0027t\nable to do the final processing required to clear PageWriteback.\n\nThe endio threads also try to exit as they become idle and\nstart more as the work piles up. The problem is that starting more\nthreads means kthreadd may need to allocate ram, and that allocation\nmay wait until the global number of writeback pages on the system is\nbelow a certain limit.\n\nThe result of that throttling is that end IO threads wait on\nkthreadd, who is waiting on IO to end, which will never happen.\n\nThis commit fixes the deadlock by handing off thread startup to a\ndedicated thread. It also fixes a bug where the on-demand thread\ncreation was creating far too many threads because it didn\u0027t take into\naccount threads being started by other procs.\n\nSigned-off-by: Chris Mason \u003cchris.mason@oracle.com\u003e\n" }, { "commit": "a99bbaf5ee6bad1aca0c88ea65ec6e5373e86184", "tree": "2b0314d68b9e0a76e8f4fb60865a1d56e138833a", "parents": [ "5e5027bd26ed4df735d29e66cd5c1c9b5959a587" ], "author": { "name": "Alexey Dobriyan", "email": "adobriyan@gmail.com", "time": "Sun Oct 04 16:11:37 2009 +0400" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sun Oct 04 15:05:10 2009 -0700" }, "message": "headers: remove sched.h from poll.h\n\nSigned-off-by: Alexey Dobriyan \u003cadobriyan@gmail.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "58e57fbd1c7e8833314459555e337364fe5521f3", "tree": "242a3859387588889c9dcc45915b0dec951f84c3", "parents": [ "8a0382f6fceaf0c6479e582e1054f36333ea3d24", "0f78ab9899e9d6acb09d5465def618704255963b" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sun Oct 04 12:39:14 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sun Oct 04 12:39:14 2009 -0700" }, "message": "Merge branch \u0027for-linus\u0027 of git://git.kernel.dk/linux-2.6-block\n\n* \u0027for-linus\u0027 of git://git.kernel.dk/linux-2.6-block: (41 commits)\n Revert \"Seperate read and write statistics of in_flight requests\"\n cfq-iosched: don\u0027t delay async queue if it hasn\u0027t dispatched at all\n block: Topology ioctls\n cfq-iosched: use assigned slice sync value, not default\n cfq-iosched: rename \u0027desktop\u0027 sysfs entry to \u0027low_latency\u0027\n cfq-iosched: implement slower async initiate and queue ramp up\n cfq-iosched: delay async IO dispatch, if sync IO was just done\n cfq-iosched: add a knob for desktop interactiveness\n Add a tracepoint for block request remapping\n block: allow large discard requests\n block: use normal I/O path for discard requests\n swapfile: avoid NULL pointer dereference in swapon when s_bdev is NULL\n fs/bio.c: move EXPORT* macros to line after function\n Add missing blk_trace_remove_sysfs to be in pair with blk_trace_init_sysfs\n cciss: fix build when !PROC_FS\n block: Do not clamp max_hw_sectors for stacking devices\n block: Set max_sectors correctly for stacking devices\n cciss: cciss_host_attr_groups should be const\n cciss: Dynamically allocate the drive_info_struct for each logical drive.\n cciss: Add usage_count attribute to each logical drive in /sys\n ...\n" }, { "commit": "0f78ab9899e9d6acb09d5465def618704255963b", "tree": "b92832da61ae4f4d712a33ae524c482e979be5ba", "parents": [ "e00c54c36ac2024c3a8a37432e2e2698ff849594" ], "author": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Sun Oct 04 21:04:38 2009 +0200" }, "committer": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Sun Oct 04 21:04:38 2009 +0200" }, "message": "Revert \"Seperate read and write statistics of in_flight requests\"\n\nThis reverts commit a9327cac440be4d8333bba975cbbf76045096275.\n\nCorrado Zoccolo \u003cczoccolo@gmail.com\u003e reports:\n\n\"with 2.6.32-rc1 I started getting the following strange output from\n\"iostat -kx 2\":\nLinux 2.6.31bisect (et2) \t04/10/2009 \t_i686_\t(2 CPU)\n\navg-cpu: %user %nice %system %iowait %steal %idle\n 10,70 0,00 3,16 15,75 0,00 70,38\n\nDevice: rrqm/s wrqm/s r/s w/s rkB/s wkB/s\navgrq-sz avgqu-sz await svctm %util\nsda 18,22 0,00 0,67 0,01 14,77 0,02\n43,94 0,01 10,53 39043915,03 2629219,87\nsdb 60,89 9,68 50,79 3,04 1724,43 50,52\n65,95 0,70 13,06 488437,47 2629219,87\n\navg-cpu: %user %nice %system %iowait %steal %idle\n 2,72 0,00 0,74 0,00 0,00 96,53\n\nDevice: rrqm/s wrqm/s r/s w/s rkB/s wkB/s\navgrq-sz avgqu-sz await svctm %util\nsda 0,00 0,00 0,00 0,00 0,00 0,00\n0,00 0,00 0,00 0,00 100,00\nsdb 0,00 0,00 0,00 0,00 0,00 0,00\n0,00 0,00 0,00 0,00 100,00\n\navg-cpu: %user %nice %system %iowait %steal %idle\n 6,68 0,00 0,99 0,00 0,00 92,33\n\nDevice: rrqm/s wrqm/s r/s w/s rkB/s wkB/s\navgrq-sz avgqu-sz await svctm %util\nsda 0,00 0,00 0,00 0,00 0,00 0,00\n0,00 0,00 0,00 0,00 100,00\nsdb 0,00 0,00 0,00 0,00 0,00 0,00\n0,00 0,00 0,00 0,00 100,00\n\navg-cpu: %user %nice %system %iowait %steal %idle\n 4,40 0,00 0,73 1,47 0,00 93,40\n\nDevice: rrqm/s wrqm/s r/s w/s rkB/s wkB/s\navgrq-sz avgqu-sz await svctm %util\nsda 0,00 0,00 0,00 0,00 0,00 0,00\n0,00 0,00 0,00 0,00 100,00\nsdb 0,00 4,00 0,00 3,00 0,00 28,00\n18,67 0,06 19,50 333,33 100,00\n\nGlobal values for service time and utilization are garbage.
