Nah², I had to remove all these:

pick a58b4da77b40920f perf dsos: Switch backing storage to array from rbtree/list 
pick 7d91cefd1fb63068 perf dsos: Remove __dsos__addnew()
pick 80c3ccf05199dbb6 perf dsos: Remove __dsos__findnew_link_by_longname_id()
pick af3f8dea24f47802 perf dsos: Switch hand code to bsearch()
pick 7537b92b48318834 perf dso: Add reference count checking and accessor functions
pick 9bd7c6fe8de22b37 perf dso: Reference counting related fixes
pick 4de57b46a0cb2027 perf dso: Use container_of() to avoid a pointer in 'struct dso_data'

Due to a bisect that pointed "perf dsos: Switch backing storage to array
from rbtree/list" as the one where:

 
root@x1:~# perf test "kernel lock contention analysis test"
 87: kernel lock contention analysis test                            : FAILED!
