Probably not, but dunno. Since this flag is only useful for a very well defined type of processes (i.e. session managers, sup... 8 Mar 2010 18:41

Hello! This patch set gets rid of read_barrier_depends() in ftrace in favor of RCU APIs, increases the RCU CPU stall timeout if CONFIG_PROVE_RCU, and fixes an x86/mce lockdep splat.

[PATCH tip/core/rcu 3/3] x86/mce: fix RCU lockdep splats
Create an rcu_dereference_check_mce() that checks for RCU-sched read side and mce_read_mutex being held on update side.

commit 554f76962d3a6eb5110415f1591aca83f96a84ae hangs USB vmware-7.0.1
Linux version v2.6.33-5399-gcc7889f with reiser3 and vmware-7.0.1 Starting vmware just hang even before displaying the main GUI. Reverting 554f76962d3a6eb5110415f1591aca83f96a84ae solves the problem. It seems vmware is trying to access the USB but this commit blocks it. So, is this a vmware problem or sh... 5 Mar 2010 18:28

Different definition in div_sc and clocksource_cyc2ns
hi, While working with the clocksource, I found that the relation of cycle and nanosecond of div_sc and clocksource_cyc2ns is different. linux-2.6.33 div_sc in include/linux/clockchips.h suggests that clock_ticks = (nanoseconds * factor) >> shift. 98/* 99 * Calculate a multiplication factor for scaled ma... 5 Mar 2010 17:21

bit errors on spitz
Hi! I'm getting way too many bit errors on spitz, with various kernels. It may be tied to network usage (bluetooth or wifi?). It happens even on AC power.
