=== <code>parasite_fuxup_vdso</code> ===

=== setns ===

The 2nd longest routine. It takes ~ 0.07 seconds on dump.

Starting from the 2nd call, setns() calls synchronize_rcu in kernel. Result -- 4 setns are 6% of 4 tests dump time.

 

=== Too many readlink-s ===

 

Some files are readlinked 3-4 times in a row.
