This patchset is combined by 3 parts:
Part 1: Bugfix (1/12 - 2/12).
Part 2: Improve BPF configuration syntax, allow BPF program set
probing options originally belong to 'perf probe'
(3/12 - 5/12)
Part 3: Allow BPF program read kernel data using variable names
and do structure dereferencing automatically.
(6/12 - 12/12)
Although not obvious, the order is need to be kept if one want to
try the testcase shown in 12/12's commit message. Otherwise he/she
should find another example, and deal with inlining problems and bugs
in perf probe.
Compare with previous patches I posted before, the main difference in
this patchset is improving commit messages and utilizing new testing
and error reporting code.
He Kuang (1):
perf tools: Add prologue for BPF programs for fetching arguments
Masami Hiramatsu (1):
