eventfs uses the tracefs_inode and assumes that it's already initialized
to zero. That is, it doesn't set fields to zero (like ti->private) after
getting its tracefs_inode. This causes bugs due to stale values.
Just initialize the entire structure to zero on

The dentry lookup for eventfs files was very broken, and had lots of
signs of the old situation where the filesystem names were all created
statically in the dentry tree, rather than being looked up dynamically
based on the eventfs data structures.

This is a tiny fix to pfn_to_virt() for some platforms.
The original implementaion of pfn_to_virt() takes PFN instead of PA as the
input to macro __va, with PAGE_SHIFT applying to the converted VA, which
is not right under most conditions, especially when there's an offset in
__va.

The trace output will also include the tracepoint name. That is, it will
have the same content but will be preceded with:

Currently there seems to be three page frag implementions
which all try to allocate order 3 page, if that fails, it
then fail back to allocate order 0 page, and each of them
all allow order 3 page allocation to fail under certain
condition by using specific gfp bits.
The gfp bits for order 3 page
The page frag in vhost_net_page_frag_refill() uses the
'struct page_frag' from skb_page_frag_refill(), but it's
implementation is similar to page_frag_alloc_align() now.
This patch removes vhost_net_page_frag_refill() by using
'struct page_frag_cache' instead of 'struct page_frag',
and allocating
introduce vhost_net_test basing on virtio_test to test
vhost_net changing in the kernel.
