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: NKay Sievers <kay.sievers@suse.de> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

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.

In commit 3D59121003721a8fad11ee72e646fd9d3076b5679c, the x86 and x86-64 <asm/param.h> was changed to include <linux/config.h> for the configurable timer frequency. However, asm/param.h is sometimes used in userland (it is included indirectly from <sys/param.h>), so your commit pollutes the userland namespace with tons of CONFIG_FOO macros. This greatly confuses software packages (such as BusyBox) which use CONFIG_FOO macros themselves to control the inclusion of optional features. After a short exchange, Christoph approved this patch Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

The below "jumbo" patch fixes the following problems in MLDv2. 1) Add necessary "ntohs" to recent "pskb_may_pull" check [breaks all nonzero source queries on little-endian (!)] 2) Add locking to source filter list [resend of prior patch] 3) fix "mld_marksources()" to a) send nothing when all queried sources are excluded b) send full exclude report when source queried sources are not excluded c) don't schedule a timer when there's nothing to report NOTE: RFC 3810 specifies the source list should be saved and each source reported individually as an IS_IN. This is an obvious DOS path, requiring the host to store and then multicast as many sources as are queried (e.g., millions...). This alternative sends a full, relevant report that's limited to number of sources present on the machine. 4) fix "add_grec()" to send empty-source records when it should The original check doesn't account for a non-empty source list with all sources inactive; the new code keeps that short-circuit case, and also generates the group header with an empty list if needed. 5) fix mca_crcount decrement to be after add_grec(), which needs its original value These issues (other than item #1 ;-) ) were all found by Yan Zheng, much thanks!

Currently a simple void foo(void) { preempt_enable(); } produces the following code on ARM: foo: bic r3, sp, #8128 bic r3, r3, #63 ldr r2, [r3, #4] ldr r1, [r3, #0] sub r2, r2, #1 tst r1, #4 str r2, [r3, #4] blne preempt_schedule mov pc, lr The problem is that the TIF_NEED_RESCHED flag is loaded _before_ the preemption count is stored back, hence any interrupt coming within that 3 instruction window causing TIF_NEED_RESCHED to be set won't be seen and scheduling won't happen as it should. 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.

Jan's crosscompile page [1] shows, that one regression in 2.6.15-rc is that the v850 defconfig does no longer compile. The compile error is: <-- snip --> ... CC arch/v850/kernel/setup.o In file included from /usr/src/ctest/rc/kernel/arch/v850/kernel/setup.c:17: /usr/src/ctest/rc/kernel/include/linux/irq.h:13:43: asm/smp.h: No such file or directory make[2]: *** [arch/v850/kernel/setup.o] Error 1 <-- snip --> The #include <asm/smp.h> in irq.h was intruduced in 2.6.15-rc. 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.

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.

The udelay() inline for ia64 uses the ITC. If CONFIG_PREEMPT is enabled and the platform has unsynchronized ITCs and the calling task migrates to another CPU while doing the udelay loop, then the effective delay may be too short or very, very long. This patch disables preemption around 100 usec chunks of the overall desired udelay time. This minimizes preemption-holdoffs. udelay() is now too big to be inline, move it out of line and export it.

In the scenario that a link was broken, the devloss timer for each rport was expire at roughly the same time, causing lots of "delete" workqueue items being queued. Depth is dependent upon the number of rports that were on the link. The rport target remove calls were calling flush_scheduled_work(), which would interrupt the stream, and start the next workqueue item, which did the same thing, and so on until recursion depth was large. This fix stops the recursion in the initial delete path, and pushes it off to a host-level work item that reaps the dead rports. Signed-off-by: NJames Bottomley <James.Bottomley@SteelEye.com>

The drawing function cfbfillrect does not work correctly when access is not unsigned-long aligned. It manifests as extra lines of pixels that are not complete drawn.

由 Knut Petersen 提交于
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: NKnut Petersen <Knut_Petersen@t-online.de> Acked-by: N"Antonino A.
