Subject: [PATCH 0/4] um: Set parent-death signal for sub-processes
The ubd io and write_sigio threads/processes may leak e.g. when
the main process is killed by "kill -9". Fix it by setting the
parent-death signal for them.
Tiwei Bie (4):
um: Add os_set_pdeathsig helper function
um: Set parent-death signal for ubd io thread/process
um: Set parent-death signal for write_sigio thread/process
um: Use os_set_pdeathsig helper in winch thread/process
