appropriate.

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.

217c4e14ea Fix several deficiencies, as compared to ptrace(2):
* Did not check for P_SUGID on ATTACH.
* Did not check for tracing of init on ATTACH.
* Did not turn off single-step mode on RUN or DETACH.
* Might have screwed up reparenting in some cases.
* Allowed anyone to detach the process.

89a4d9a733 don't try to use __builtin_return_address() on the Alpha. (It's never
worked as far as I can tell, and apparently crashes the kernel when
invoked here.)  From Ross Harvey, PR#3471.

90688fce27 Change the second and third args to struct vfsops' (*vfs_mount)() to
'const char *', and 'void *', respectively.  The second arg is taken directly
from user arguments, and is const there, so must be const in the prototypes
and functions.  The third arg is also taken directly from user arguments.
It doesn't have to be changed, but since it's cleaner to keep the type
the same as the user arg's type, and I'm already making the 'const char *'
change...

fce3e0874f Fix vop_link, vop_symlink, and vop_remove semantics in several ways:
* Change the argument names to vop_link so they actually make sense.
* Implement vop_link and vop_symlink for all file systems, so they do proper
  cleanup.
* Require the file system to decide whether or not linking and unlinking of
  directories is allowed, and disable it for all current file systems.
