With a debug\npatch adding proper reverse links and stack trace logging in ext3 deployed\nin production, I found journal_stop is never run because\nmark_inode_dirty_sync is called inside release_task called by do_exit.\n(that was quite fun because I would have never thought about this\nsubtleness, I thought a regular path in ext3 had a bug and it forgot to\ncall journal_stop)\n\ndo_exit-\u003erelease_task-\u003emark_inode_dirty_sync-\u003eschedule() (will never\ncome back to run journal_stop)\n\nThe reason is that shrink_dcache_parent is racy by design (feature not\na bug) and it can do blocking I/O in some case, but the point is that\ncalling shrink_dcache_parent at the last stage of do_exit isn\u0027t safe\nfor self-reaping tasks.\n\nI guess the memory pressure of the unbalanced highmem system allowed\nto trigger this more easily.\n\nNow mainline doesn\u0027t have this line in iput (like sles9 has):\n\n \t if (inode-\u003ei_state \u0026 I_DIRTY_DELAYED)\n\t \t\t\tmark_inode_dirty_sync(inode);\n\nso it will probably not crash with ext3, but for example ext2 implements an\nI/O-blocking ext2_put_inode that will lead to similar screwups with\next2_free_blocks never coming back and it\u0027s definitely wrong to call\nblocking-IO paths inside do_exit.

The \"clockid\"\nparameter can be either CLOCK_MONOTONIC or CLOCK_REALTIME.\n\nThe timerfd_settime() API give new settings by the timerfd fd, by optionally\nretrieving the previous expiration time (in case the \"otmr\" parameter is not\nNULL).\n\nThe time value specified in \"utmr\" is absolute, if the TFD_TIMER_ABSTIME bit\nis set in the \"flags\" parameter. Otherwise it\u0027s a relative time.\n\nThe timerfd_gettime() API returns the next expiration time of the timer, or\n{0, 0} if the timerfd has not been set yet.\n\nLike the previous timerfd API implementation, read(2) and poll(2) are\nsupported (with the same interface).
