Here we use the hugetlbfs tracepoint to track the call stack. And
the output in trace is as follows:
```
touch-5265[005] .43.246550: hugetlbfs_alloc_inode: dev 0,51 ino
24621 dir 21959 mode 0100644
touch-5265[005] .43.246638: hugetlbfs_setattr: dev 0,51 ino
24621 na
Add basic tracepoints for {alloc, evict, free}_inode, setattr and
fallocate. These can help users to debug hugetlbfs more conveniently.

Here we add some basic tracepoints for debugging hugetlbfs: {alloc, free,

v2 can be found at:

Changes since v2:
- Simplify the tracepoint output for setattr.
- Make every token be space s

Currently, the show_inode_state() macro only prints
part of the state of inode->i_state. Let’s improve it
to display more of its state.
