+	* CFS:
+	- Re-enable lockless sct_flags. (#ifdef SVRCFSTOK_SCT_FLAGS_NOLOCK)
+
+	* VPROC:
+	- Fix select_bad_process() NULL p_vproc pointer dereference.
+	- Fix de_thread() related issues:
+	  - Fix de_thread() calling VPOP_RECLAIM_CHILD() while holding
+	    spin_lock(task->proc_lock). Code path might sleep.
+	  - Fix NULL p_vproc pointer dereference when thread group leader is
+	    exiting, has PF_FORKNOEXEC flag, and has lost race with
+	    de_thread(). Affects exit_notify(), forget_original_parent(), and
+	    will_become_orphaned_pgrp(). When p_vproc is NULL the exiting
+	    process reaps itself.
+	  - Fix dpvproc_nocldwait_async_handler() NULL pointer dereference due
+	    to failed lookup for vproc of new parent when lost race with
+	    de_thread(). (#ifdef RELEASE_TASK_LEADER_GONE__VPROC_FIX)
+	  - New PVPOP_SWITCH_PID() to switch VProc PID of process doing
+	    de_thread().
+	  - New PV_DETHREAD_REAP flag is set during de_thread() to indicate to
+	    child reaper to reap thread group leader without delay.
+	  - Fix oops in do_notify_resume() path due to NULL pointer
+	    dereference. p_vproc is NULL after bad fork.
+
+	* VPROC (#ifdef VPROC_RELEASE__REFCNT_RACE_FIX):
+	- Fix extra VPROC_RELE() on PVPOP_RMV_PGRP_LIST() -ESRCH error.
+	- Fix PVPOP_REAP() extra dpvproc_remove_pgrp_leader_member_care() on
+	  PVPOP_RMV_PGRP_LIST() -EBUSY error; was typo in if-test.
+	- PVPOP_REAP() no longer does async PVPOP_RMV_PGRP_LIST(); now sync.
+	  Don't see how reaping parent can hold PGRP LOCK in PVPOP_REAP() path.
+	- Fix exit_vproc() did not decrement vproc reference for process group
+	  leader on member node. This is in do_fork() error path.
+
+	* VPROC (#ifdef VPROC_CONTINUE):
+	- Fix dpvproc_nocldwait_async_handler() deadlock on PVPOP_REAP() -EBUSY
+	  due to delay_group_leader(). PV_REAPER_RETRY flag is set and group
+	  leader is re-inserted into the queue so that the remaining threads in
+	  thread group can be reaped by this handler to remove the
+	  delay_group_leader() condition.
+	- Regression:
+	  - Fix pproc_reap() should succeed, but returns -EBUSY when process is
+	    a thread group leader in non-empty thread group and is already in
+	    EXIT_DEAD state.
+
+	* Files in ci-linux project were modified (see ci/ChangeLog).
