Author: dchagin Date: Sat Jan 9 14:36:44 2016 New Revision: 293480 URL: https://svnweb.freebsd.org/changeset/base/293480 Log: MFC r283372: In preparation for switching linuxulator to the use the native 1:1 threads split sys_thr_exit() up into sys_thr_exit() and kern_thr_exit(). Move Where the second will be used in linux_exit() system call later.
