* sysfs: use ilookup5() instead of ilookup5_nowait()Tejun Heo2008-10-161-9/+8
| | | | | | | | | | | | | | | As inode creation is protected by sysfs_mutex, ilookup5_nowait() always either fails to find at all or finds one which is fully initialized, so using ilookup5_nowait() or ilookup5() doesn't make any difference. Switch to ilookup5() as it's planned to be removed. This change also makes lookup return value handling a bit simpler. This change was suggested by Al Viro.

* usb: turn dev_warn+WARN_ON combos into dev_WARNArjan van de Ven2008-10-161-16/+8

* debug: use dev_WARN() rather than WARN_ON() in device_pm_add()Arjan van de Ven2008-10-161-1/+1
| | | | | | | | | | | | | | | device_pm_add() has a WARN_ON that is showing relatively high on kerneloops.org, but unfortunately the WARN_ON is less than useful in that it doesn't print any information about what device is causing the issue. This patch fixes this by turning the WARN_ON() into the newly introduces dev_WARN() which will print information about the device in question.

* debug: Introduce a dev_WARN() functionArjan van de Ven2008-10-161-0/+8
| | | | | | | | | | | | in the line of dev_printk(), this patch introduces a dev_WARN() function, that takes a struct device and then a printk format/args set of arguments. Unlike dev_printk(), the effect is that of WARN() in that a full warning message (including filename/line, module list, versions and a backtrace) is printed in addition to the device name and the arguments.

Yes, it is a real bug by the looks. bin.c takes bb->mutex under mmap_sem when it is mmapped, and then does its copy_*_user under bb->mutex too. Here is a basic fix for the sysfs lor.

* device model: Do a quickcheck for driver binding before doing an expensive checkArjan van de Ven2008-10-161-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a quick check for the driver<->device match before taking the locks and doin gthe expensive checks. Taking the lock hurts in asynchronous boot context where the device lock gets hit; one of the init functions takes the lock and goes to do an expensive hardware init; the other init functions walk the same PCI list and get stuck on the lock as a result. For the common case, we can know there's no chance whatsoever of a match if the device isn't in the drivers ID table... so this patch does that check as a best-effort-avoid-the-lock approach. Bootcharts for before and after can be seen at http://www.fenrus.org/before.svg http://www.fenrus.org/after.svg Note the long time "agp_ali_init" takes in the first graph; my laptop doesn't even have an ALI chip in it! (the bootgraphs look a bit dissimilar, but that's the point, the first one has a bunch of arbitrary delays in it that cause it to look very different) This reduces my kernel boot time by about 20% Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Cc: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* sysfs: Support sysfs_notify from atomic context with new sysfs_notify_direntNeil Brown2008-10-165-18/+62
| | | | | | | | | | | | | | | | | | | | | | | | | Support sysfs_notify from atomic context with new sysfs_notify_dirent sysfs_notify currently takes sysfs_mutex. This means that it cannot be called in atomic context. sysfs_mutex is sometimes held over a malloc (sysfs_rename_dir) so it can block on low memory. In md I want to be able to notify on a sysfs attribute from atomic context, and I don't want to block on low memory because I could be in the writeout path for freeing memory. So: - export the "sysfs_dirent" structure along with sysfs_get, sysfs_put and sysfs_get_dirent so I can get the sysfs_dirent that I want to notify on and hold it in an md structure. - split sysfs_notify_dirent out of sysfs_notify so the sysfs_dirent can be notified on with no blocking (just a spinlock).

* driver core: basic infrastructure for per-module dynamic debug messagesJason Baron2008-10-1614-7/+700
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Base infrastructure to enable per-module debug messages. I've introduced CONFIG_DYNAMIC_PRINTK_DEBUG, which when enabled centralizes control of debugging statements on a per-module basis in one /proc file, currently, <debugfs>/dynamic_printk/modules. When, CONFIG_DYNAMIC_PRINTK_DEBUG, is not set, debugging statements can still be enabled as before, often by defining 'DEBUG' for the proper compilation unit. Thus, this patch set has no affect when CONFIG_DYNAMIC_PRINTK_DEBUG is not set. The infrastructure currently ties into all pr_debug() and dev_dbg() calls. That is, if CONFIG_DYNAMIC_PRINTK_DEBUG is set, all pr_debug() and dev_dbg() calls can be dynamically enabled/disabled on a per-module basis. Future plans include extending this functionality to subsystems, that define their own debug levels and flags. Usage: Dynamic debugging is controlled by the debugfs file, <debugfs>/dynamic_printk/modules. This file contains a list of the modules that can be enabled. The format of the file is as follows: <module_name> <enabled=0/1> . . . <module_name> : Name of the module in which the debug call resides <enabled=0/1> : whether the messages are enabled or not For example: snd_hda_intel enabled=0 fixup enabled=1 driver enabled=0 Enable a module: $echo "set enabled=1 <module_name>" > dynamic_printk/modules Disable a module: $echo "set enabled=0 <module_name>" > dynamic_printk/modules Enable all modules: $echo "set enabled=1 all" > dynamic_printk/modules Disable all modules: $echo "set enabled=0 all" > dynamic_printk/modules Finally, passing "dynamic_printk" at the command line enables debugging for all modules. This mode can be turned off via the above disable command.

| * MIPS: PCI: Scan busses when they are registeredAurelien Jarno2008-10-151-27/+53
| | | | | | | | | | | | | | | | | | | | | | The patch below changes register_pci_controller() such that controllers being added after pcibios_init() has run are be scanned immediately. This is needed for example by the BCM47xx PCI controller, which is located on the SSB bus, which is now initialized after the PCI subsystem.
