+What: noswapaccount kernel command line parameter
+When: 2.6.40
+Why: The original implementation of memsw feature enabled by
+ CONFIG_CGROUP_MEM_RES_CTLR_SWAP could be disabled by the noswapaccount
+ kernel parameter (introduced in 2.6.29-rc1). Later on, this decision
+ turned out to be not ideal because we cannot have the feature compiled
+ in and disabled by default and let only interested to enable it
+ (e.g. general distribution kernels might need it). Therefore we have
+ added swapaccount[=0|1] parameter (introduced in 2.6.37) which provides
+ the both possibilities. If we remove noswapaccount we will have
+ less command line parameters with the same functionality and we
+ can also cleanup the parameter handling a bit ().
