Not at all! it's always our great pleasure that we could help developers to
root cause problems then improve linux kernel code quality.

commit:

since 7408e24933084's data is similar to b4cc0734d2574, and 3f99656f7bc2f's data
is similar to 20f7d1936e8a2 (which is a little better here), we guess the
  3f99656f7bc2f step 5: call __dentry_kill() without holding a lock on parent
is the major reason for regression.
so in below [1] full comparison, I just give out profiles of 7408e24933084
and 3f99656f7bc2f. just let us know if you need data for other two commits
or you need more results from other commits in this set.

we saw similar results that 3f99656f7bc2f seems be the major reason for
regression.
in below [2] full comparison, just give results for 7408e24933084 and
3f99656f7bc2f.
