This is a problem because right after creation\na) PDE is fully visible in /proc , and\nb) -\u003eproc_fops are proc_file_operations which do not have -\u003eopen callback. So, it\u0027s\n possible to -\u003eread without -\u003eopen (see one class of oopses below).\n\nThe fix is new API called proc_create() which makes sure -\u003eproc_fops are\nset up before gluing PDE to main tree.

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. So this should fix a subtle bug in\nmainline too (not verified in practice though). The equivalent fix for\next3 is also not verified yet to fix the problem in sles9 but I don\u0027t have\ndoubt it will (it usually takes days to crash, so it\u0027ll take weeks to be\nsure).\n\nAn alternate fix would be to offload that work to a kernel thread, but I\ndon\u0027t think a reschedule for this is worth it, the vm should be able to\ncollect those entries for the synchronous release_task.\n\nSigned-off-by: Andrea Arcangeli \u003candrea@suse.de\u003e\nCc: Jan Kara \u003cjack@ucw.cz\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: \"Eric W.

So a proper d_revalidate method that calls d_drop\nalso needs to call have_submounts which is moderately expensive, so you\nreally don\u0027t want a d_revalidate method that unconditionally calls it, but\ninstead only calls it when the backing object has really gone away.\n\nproc generic entries only disappear on module_unload (when not counting the\nfledgling network namespace) so it is quite rare that we actually encounter\nthat case and has not actually caused us real world trouble yet.\n\nSo until we get a proper test for keeping dentries in the dcache fix the\ncurrent d_revalidate method by completely removing it. This returns us to\nthe current status quo.\n\nSo with CONFIG_NETNS\u003dn things should look as they have always looked.\n\nFor CONFIG_NETNS\u003dy things work most of the time but there are a few rare\ncorner cases that don\u0027t behave properly.
