[PATCH] tracing/events: Add bounce tracing to swiotbl-xen
...hen
xen_swiotlb_map_page() doesn't stop after range_straddles_page_boundary(), but
calls spinlock functions, memcpy() and xen_phys_to_bus() as well. This patch
introduces the swiotlb-xen:bounced event, which also prints out the following
informations to help you find out why bouncing happened:
dev_name: 0000:08:00.0 dma_mask=ffffffffffffffff dev_addr=9149f000 size=32768
swiotlb_force=0
If (dev_addr + size + 1) > dma_mask, the buffer is out of the device's DMA
range. If swiotlb_force == 1, you should really change the kernel parameters.
Otherwise, the buffer is not contiguous in mfn space...

[PATCH v8 1/6] daemon: Changing the way that we detect if a device contains partitions.
Instead of using part_to_dev to find such devices we open the device's
directory under /sys/block/<dev_name> and look for entries starting with
<dev_name>, eg. /sys/block/sda/sda1.

give me some works
hello, Chris
In the next several months, I will have a lot of spare time. I will
be happy if you assign some work to me. I have learn linux kernel
for years but only fix a few small bugs in IP stack. In the past few
months, I read some EXT4/VFS codes. I began reading source of btrfs
ten days ago and have read it twice now.
Regards
YZ
