Yes :

# git describe --contains f2c31e32b378a6653f
v3.1-rc1~24^2~11

It all depends if f2c31e32b378a6653f is backported to 3.0 someday, since
it fixes bug added in commit f39925dbde778 (ipv4: Cache learned redirect
information in inetpeer)

# git describe --contains  f39925dbde778  
v2.6.39-rc1~468^2~349
