[PATCH 1/2] unshare system call: System Call handler function sys_unshare


Given the complexity of the kernel code involved and the obscurity of
the functionality why not just do another clone() in userspace to
unshare the things you want to unshare and then _exit the parent ?

suppose somebody wait()s for the parent? you've turned a synchronous operation into an asynchronous one.
