The patch titled memsw: handle swapaccount kernel parameter correctly has been removed from the -mm tree. Its filename was memsw-handle-swapaccount-kernel-parameter-correctly.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: memsw: handle swapaccount kernel parameter correctly From: Michal Hocko <mhocko@xxxxxxx> __setup based kernel command line parameters handlers which are handled in obsolete_checksetup are provided with the parameter value including = (more precisely everything right after the parameter name). This means that the current implementation of swapaccount[=1|0] doesn't work at all because if there is a value for the parameter then we are testing for "0" resp. "1" but we are getting "=0" resp. "=1" and if there is no parameter value we are getting an empty string rather than NULL. The original noswapccount parameter, which doesn't care about the value, works correctly.
