The patch titled
taskstats: fix sk_buff size calculation
has been removed from the -mm tree. Its filename was
taskstats-fix-sk_buff-size-calculation.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: taskstats: fix sk_buff size calculation
From: Oleg Nesterov <oleg@xxxxxxxxxx>
prepare_reply() adds GENL_HDRLEN to the payload (genlmsg_total_size()), but
then it does genlmsg_put()->nlmsg_put(). This means we forget to reserve a
room for 'struct nlmsghdr', no?
