Hey Thomas, I just wanted to send you my pending queue of timekeeping change for 2.6.36. It would be nice to get these into the -tip tree for testing prior to the merge window. thanks -john CC: Thomas Gleixner <tglx(a)linutronix.de> John Stultz (11): x86: Fix vtime/file timestamp inconsistencies Im... 13 Jul 2010 21:56

[PATCH 02/11] Implement timespec_add
After accidentally misusing timespec_add_safe, I wanted to make sure we don't accidently trip over that issue again, so I created a simple timespec_add() function which we can use to replace the instances of timespec_add_safe() that don't want the overflow detection.

[PATCH 2.6.35-rc1] net-next: vmxnet3 fixes [5/5] Respect the interrupt type in VM configuration
Do not ignore interrupt type in VM configuration When interrupt type is not auto, do not ignore the interrupt type set from VM configuration. Driver may not always respect the interrupt type in configuration but it will certainly try to. Eg: if MSIx is configured and enabling MSIx fails in driver, it fall ba... 13 Jul 2010 21:56

[PATCH 2.6.35-rc1] net-next: vmxnet3 fixes [4/5] Do not reset when the device is not opened
Do not reset when the device is not opened If a reset is scheduled, and the device goes thru close and open, it may happen that reset and open may run in parallel. The reset code now bails out if the device is not opened. Signed-off-by: Ronghua Zang <ronghua(a)vmware.com> Signed-off-by: Matthieu Bucchianeri <... 13 Jul 2010 20:50

[PATCH 2.6.35-rc1] net-next: vmxnet3 fixes [2/5] Interrupt control bitmap
A new bit map 'intrCtrl' is introduced in the DriverShared area. The driver should update VMXNET3_IC_DISABLE_ALL bit before writing IMR.

[PATCH 2.6.35-rc1] net-next: vmxnet3 fixes [3/5] Initialize link state at probe time
Initialize vmxnet3 link state at probe time This change initializes the state of link at the time when driver is loaded. The ethtool output for 'link detected' and 'link speed' is thus valid even before the interface is brought up.

CFQ: Don't store left slice when slice used up or for a idle workload
