The patch titled
Subject: kernel/sysctl.c: add kdoc comments to do_proc_do{u}intvec_minmax_conv_param
has been removed from the -mm tree. Its filename was

From: Waiman Long <longman@xxxxxxxxxx>
Subject: kernel/sysctl.c: add kdoc comments to do_proc_do{u}intvec_minmax_conv_param
Kdoc comments are added to the do_proc_dointvec_minmax_conv_param and
do_proc_douintvec_minmax_conv_param structures thare are used internally
for range checking.
The error codes returned by proc_dointvec_minmax() and
proc_douintvec_minmax() are also documented.
