Here we add some basic tracepoints for debugging hugetlbfs: {alloc, free,
evict}_inode, setattr and fallocate.

v2 can be found at:
https://lore.kernel.org/all/ZoYY-sfj5jvs8UpQ@casper.infradead.org/T/

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


v1 can be found at:
https://lore.kernel.org/linux-mm/20240701194906.3a9b6765@gandalf.local.home/T/

Changes since v1:
  - Decrease the parameters for setattr tracer suggested by Steve and Mathieu.
  - Replace current_user_ns() with init_user_ns when translate uid/gid.

Hongbo Li (2):
  hugetlbfs: support tracepoint
  hugetlbfs: use tracepoints in hugetlbfs functions.
