* [PATCH] driver core: replace "hotplug" by "uevent"Kay Sievers2006-01-04
| | | | | | | | | Leave the overloaded "hotplug" word to susbsystems which are handling real devices. The driver core does not "plug" anything, it just exports the state to userspace and generates events.

* [PATCH] merge kobject_uevent and kobject_hotplugKay Sievers2006-01-04
| | | | | | | | | | | | | | | | | | | | The distinction between hotplug and uevent does not make sense these days, netlink events are the default. udev depends entirely on netlink uevents. Only during early boot and in initramfs, /sbin/hotplug is needed. So merge the two functions and provide only one interface without all the options. The netlink layer got a nice generic interface with named slots recently, which is probably a better facility to plug events for subsystem specific events. Also the new poll() interface to /proc/mounts is a nicer way to notify about changes than sending events through the core. The uevents should only be used for driver core related requests to userspace now. Signed-off-by: Kay Sievers <kay.sievers@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* [PATCH] remove mount/umount uevents from superblock handlingKay Sievers2006-01-04
| | | | | | | | | | | | The names of these events have been confusing from the beginning on, as they have been more like claim/release events. We needed these events for noticing HAL if storage devices have been mounted. Thanks to Al, we have the proper solution now and can poll() /proc/mounts instead to get notfied about mount tree changes.

Nothing currently prevents gcc from performing that reordering. There is already a barrier() before the decrement of the preemption count, but another one is needed between this and the TIF_NEED_RESCHED flag test for proper code ordering.

The compile error is: <-- snip --> ...

Since include/linux/irq.h needs code from asm/smp.h only in the CONFIG_SMP=y case and linux/smp.h #include's asm/smp.h only in the CONFIG_SMP=y case, I'm suggesting this patch to #include <linux/smp.h> in irq.h.

* | [PATCH] relayfs: remove warning printk() in relay_switch_subbuf()Tom Zanussi2005-12-20
|/ | | | | | | | | | | | | | | | | There's currently a diagnostic printk in relay_switch_subbuf() meant as a warning if you accidentally try to log an event larger than the sub-buffer size. The problem is if this happens while logging from somewhere it's not safe to be doing printks, such as in the scheduler, you can end up with a deadlock. This patch removes the warning from relay_switch_subbuf() and instead prints some diagnostic info when the channel is closed.

* [PATCH] fbdev: fix switch to KD_TEXT, enhanced versionKnut Petersen2005-12-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Every framebuffer driver relies on the assumption that the set_par() function of the driver is called before drawing functions and other functions dependent on the hardware state are executed. Whenever you switch from X to a framebuffer console for the very first time, there is a chance that a broken X system has _not_ set the mode to KD_GRAPHICS, thus the vt and framebuffer code executes a screen redraw and several other functions before a set_par() is executed. This is believed to be not a bug of linux but a bug of X/xdm. At least some X releases used by SuSE and Debian show this behaviour. There was a 2nd case, but that has been fixed by Antonino Daplas on 10-dec-2005. This patch allows drivers to set a flag to inform fbcon_switch() that they prefer a set_par() call on every console switch, working around the problems caused by the broken X releases. The flag will be used by the next release of cyblafb and might help other drivers that assume a hardware state different to the one used by X. As the default behaviour does not change, this patch should be acceptable to everybody. Signed-off-by: Knut Petersen <Knut_Petersen@t-online.de> Acked-by: "Antonino A.

IN_DONT_FOLLOW -- don't follow a symlink. In combination with IN_ONLYDIR we can make sure that we don't watch the target of symlinks.
