Subject: pid namespaces: rename child_reaper() function
X-Git-Tag: firefly_0821_release~24855
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=88f21d818255bc61c002478d21caf52f8a9b8def;p=firefly-linux-kernel-4.4.55.git

pid namespaces: rename child_reaper() function

Rename the child_reaper() function to task_child_reaper() to be similar to
other task_* functions and to distinguish the function from 'struct
pid_namspace.child_reaper'.
