This patch allows relay channels to be reset i.e. unconsumed. Basically allows a 'rewind' function for flight-recorder tracing.

Hi Peter, Thanks for trying to spell it out for me. :-) Maybe... 1/ Memory is used a/ in caches, such as the fragment cache and the route cache b/ in transient allocations on their way from one place to another. e.g. network card to fragment cache, frag cache to socket. The caches can (do?) impose a natural limit on the amount of memory they use. The transient allocations should be satisfied from the normal low watermark pool. When we a...

Split the FPU save area from the task struct. This allows easy migration of FPU context, and it's generally cleaner. It also allows the following two optimizations: 1) only allocate when the application actually uses FPU, so in the first lazy FPU trap. This could save memory for non-fpu using apps. Next patch does this lazy allocation. 2) allocate the right size for the actual cpu rather than 512 bytes always. Patches enabling xsave/xrstor support (coming shortly) will take advantage of this. ...

This needs to go into 2.6.25. Thanks. --- This bug is introduced by the recent i387 merge. Current usage of unlazy_fpu() in ptrace specific routines is wrong. unlazy_fpu() will not init fpu if the task never used math. So the ptrace calls can expose the parent tasks FPU data in some cases. Replace it with the init_fpu() which will init the math state, if the task never used math before. Signed-off-by: Suresh Siddha <suresh.b.siddha@intel.com> --- diff --git a/arch/x86/kernel/i387.c...

Could you hide the asm inside an actual function and annotate the function with __used? Similar to how the kprobes has a function called kretprobe_trampoline_holder for their trampoline asm? arch/x86/kernel/kprobes.c line 584 Cheers, Harvey --

unless you're not seeing rx_no_buffer_count increase in the `ethtool -S ethx` your cpu is round-robinning network interrupts which is bad, turn the in-kernel because that device is not going to be supported by e1000e until 2.6.25. you're just use the defaults for e1000 please, unless those defaults don't work - and then it's a bug. I don't think e1000 is the issue here, I've definately not seen any reports of e1000+pptp giving issues. perhaps one of the pptp/pppd developers can look at...
