The callback is\nperformed before each freeing of an object.\n\nI would think that it is much easier to check the object state manually\nbefore the free. That also places the check near the code object\nmanipulation of the object.\n\nAlso the SLAB_DEBUG_INITIAL callback is only performed if the kernel was\ncompiled with SLAB debugging on. If there would be code in a constructor\nhandling SLAB_DEBUG_INITIAL then it would have to be conditional on\nSLAB_DEBUG otherwise it would just be dead code. But there is no such code\nin the kernel. I think SLUB_DEBUG_INITIAL is too problematic to make real\nuse of, difficult to understand and there are easier ways to accomplish the\nsame effect (i.e. add debug code before kfree).\n\nThere is a related flag SLAB_CTOR_VERIFY that is frequently checked to be\nclear in fs inode caches.

But it has the nice virtue that the assiation with a session only\nlasts until the session leader exits. Which means that no reference counting\nis required. So using struct pid winds up being a simple optimization to\navoid hash table lookups.\n\nIn the long term the use of pid_nr also ensures that when we have multiple pid\nspaces mixed everything will work correctly.\n\nSigned-off-by: Eric W.

On the FRV arch, removing the regs parameter\nfrom all the genirq function results in a 20% speed up of the IRQ exit path\n(ie: from leaving timer_interrupt() to leaving do_IRQ()).\n\nWhere appropriate, an arch may override the generic storage facility and do\nsomething different with the variable. On FRV, for instance, the address is\nmaintained in GR28 at all times inside the kernel as part of general exception\nhandling.\n\nHaving looked over the code, it appears that the parameter may be handed down\nthrough up to twenty or so layers of functions. Consider a USB character\ndevice attached to a USB hub, attached to a USB controller that posts its\ninterrupts through a cascaded auxiliary interrupt controller. A character\ndevice driver may want to pass regs to the sysrq handler through the input\nlayer which adds another few layers of parameter passing.\n\nI\u0027ve build this code with allyesconfig for x86_64 and i386. I\u0027ve runtested the\nmain part of the code on FRV and i386, though I can\u0027t test most of the drivers.\nI\u0027ve also done partial conversion for powerpc and MIPS - these at least compile\nwith minimal configurations.\n\nThis will affect all archs. Mostly the changes should be relatively easy.\nTake do_IRQ(), store the regs pointer at the beginning, saving the old one:\n\n\tstruct pt_regs *old_regs \u003d set_irq_regs(regs);\n\nAnd put the old one back at the end:\n\n\tset_irq_regs(old_regs);\n\nDon\u0027t pass regs through to generic_handle_irq() or __do_IRQ().\n\nIn timer_interrupt(), this sort of change will be necessary:\n\n\t-\tupdate_process_times(user_mode(regs));\n\t-\tprofile_tick(CPU_PROFILING, regs);\n\t+\tupdate_process_times(user_mode(get_irq_regs()));\n\t+\tprofile_tick(CPU_PROFILING);\n\nI\u0027d like to move update_process_times()\u0027s use of get_irq_regs() into itself,\nexcept that i386, alone of the archs, uses something other than user_mode().\n\nSome notes on the interrupt handling in the drivers:\n\n (*) input_dev() is now gone entirely. The regs pointer is no longer stored in\n the input_dev struct.\n\n (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does\n something different depending on whether it\u0027s been supplied with a regs\n pointer or not.\n\n (*) Various IRQ handler function pointers have been moved to type\n irq_handler_t.\n\nSigned-Off-By: David Howells \u003cdhowells@redhat.com\u003e\n(cherry picked from 1b16e7ac850969f38b375e511e3fa2f474a33867 commit)\n" }, { "commit": "1a657f78dcc8ea7c53eaa1f2a45ea2315738c15f", "tree": "a19972027792082fed505c8d540f7d877e37c0ab", "parents": [ "1c0d04c9e44f4a248335c33d2be7c7f7b06ff359" ], "author": { "name": "Oleg Nesterov", "email": "oleg@tv-sign.ru", "time": "Mon Oct 02 02:18:59 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Mon Oct 02 07:57:25 2006 -0700" }, "message": "[PATCH] introduce get_task_pid() to fix unsafe get_pid()\n\nproc_pid_make_inode:\n\n\tei-\u003epid \u003d get_pid(task_pid(task));\n\nI think this is not safe. get_pid() can be preempted after checking \"pid\n!\u003d NULL\".
