detect online disk resize
|
| |
This is version 2 of a patch series I submitted back in May 2008. This version now checks for device size changes in the rescan_partitions() routine. Which in turn is called when a device is opened and in the BLKRRPART ioctl. I am resubmitting this patch series as I got little response the previous time. Al Viro has told me offline that he would look at it this... more »

UML and sched: Annotate stacks
|
| |
Track and tell valgrind about kernel mode stacks. Valgrind gets confused without these annotations because it expects processes to only use their initial stack and stacks created for threads by way of clone.

Added flush_disk to factor out common buffer cache flushing code.

Added flush_disk to factor out common buffer cache flushing code. We need to be able to flush the buffer cache for for more than just when a disk is changed, so we factor out common cache flush code in check_disk_change() to an internal flush_disk() routine. This routine will then be used for both disk changes and disk resizes (in a... more »

ide: Two fixes regarding memory allocation
|
| |
In function ide_devset_execute() we should use __GFP_WAIT rather than GFP_KERNEL. Also, the allocation cannot possibly fail at that point. More importantly, there is a potential memory leak in the device probing code. The infrastructure seems rather complex and I hope I haven't messed anything up by trying to fix this.... more »

kmemcheck updates for tip/kmemcheck
|
| |
Hi Ingo, A rather large update, most of it is implementing the correct REP MOVS/STOS handling on P4s. I've tested it on both 32-bit and 64-bit and everything seems good! Also included is the DMA API hooks which prevents false-positive reports from reads in DMA-able memory.
