X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=b1beb91b0e20568a767b8ab50e131074316b66b7;p=openwrt%2Fstaging%2Fblogic.git staging/lustre: fix misuse of current->parent. current->parent is used by ptrace to redirect some signal delivery to the ptracer. It should only be used by 'ptrace' or 'signal' code. All other users should use current->real_parent, which is the real parent.
