- tracing/probes: Adding new pseudo-types %pd and %pD support for dumping
dentry name from 'struct dentry *' and file name from 'struct file *'.
- uprobes: Some performance optimizations have been done.
. Speed up the BPF uprobe event by delaying the fetching of the uprobe
event arguments that are not used in BPF.
. Avoid locking by speculatively checking whether uprobe event is valid.
. Reduce lock contention by using read/write_lock instead of spinlock for
uprobe list operation. This improved BPF uprobe benchmark result 43% on
average.
- rethook: Removes non-fatal warning messages when tracing stack from BPF
and skip rcu_is_watching() validation in rethook if possible.
- objpool: Optimizing objpool (which is used by kretprobes and fprobe as
rethook backend storage) by inlining functions and avoid caching nr_cpu_ids
because it is a const value.
- fprobe: Add entry/exit callbacks types (code cleanup)
- kprobes: Check ftrace was killed in kprobes if it uses ftrace.
