Fair point, "free_inode" no longer matches where it fires. I'd keep this patch as is, though, since it is tagged for stable: the event name is visible to users in tracefs (events/hugetlbfs/hugetlbfs_free_inode), and renaming it in stable kernels would break existing tracing setups there just to fix the use-after-free. I can send a follow-up on top of it for mm-unstable that renames the event to hugetlbfs_destroy_inode, which also matches the hugetlbfs_evict_inode name next to it. Would that work for you, or would you prefer the rename folded into a v2? Thanks, Joas
