e3f99a9397 Pass the vnode type to vaccess(), and use it when checking VEXEC. Make sure 
that the mode bits passed to vaccess() and returned by foo_getattr() contain
only permission bits.

07ba5e5ac3 Snapshot of namei() cleanup: 
1) Eliminate all of the null component name special cases; handle runs of
slashes and leading and trailing slashes completely differently.
2) Return ENOENT when doing a lookup through an empty symlink.
3) Enforce that we're doing a lookup through a directory in in chdir() and
lookup() rather than in foo_lookup().

Not yet finished.

8f5978a181 GC VS[UG]ID and VSVTX, and add a new VLOOKUP, since the semantics are now 
different from VEXEC.

2b65c6c346 Delay turning off P_TRACED until the process is actually waited on. It can't 
have any signals delivered while exiting, so this should be okay.  Change the
test for a traced process in wait4() to exclude a process that was started by
the debugger; in this case, only one SIGCHLD should be delivered.

701f15db33 Reinstate P_FSTRACE, with different semantics: 
* Never send a SIGCHLD to the parent if P_FSTRACE is set.
* Do not permit mixing ptrace(2) and procfs; only permit using the one that
  was attached.

6911ff7d13 Fix two performance issues: 
* When a delayed write buffer falls off the LRU queue, arrange for it to go on
  the AGE queue after being flushed out to disk.

  the LRU queue.

43bd8d5456 POSIX.1 changes to namei():

	(2) by stripping off trailing slashes and setting a `forcedir'
	    flag, make code such as {  mkdir("dir", m); rmdir("dir/"); }
	    actually work.
