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@xxxxxxxxxxxxxxxxxxxx/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@xxxxxxxxxxxxxxxxxx/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.
