2025-01-13	hugetlb: fix NULL pointer dereference in trace_hugetlbfs_alloc_inode	Muchun Song	1	-1/+1
	hugetlb_file_setup() will pass a NULL @dir to hugetlbfs_get_inode(), so we will access a NULL pointer for @dir. Fix it and set __entry->dr to 0 if @dir is NULL. Because ->i_ino cannot be 0 (see get_next_ino()), there is no confusing if user sees a 0 inode number.

2024-09-17	hugetlbfs: support tracepoint	Hongbo Li	1	-0/+156
	Add basic tracepoints for {alloc, evict, free}_inode, setattr and fallocate. These can help users to debug hugetlbfs more conveniently.
