e_tracesig used to be implemented for Darwin compat. Nowadays the Darwin
compatiblity layer is gone and there are no other users.
This functionality isn't used where it shall be used in the existing
codebase.
If we want to emulate debugging interfaces in compat layers we would need
to implement that from scratch anyway. We would need to be bug compatible
with other OSes too.
Proposed on tech-kern@.
Welcome to NetBSD 8.99.16!

This system call was used in legacy Lisp code, that was inherited to modern
age and still compiled against supported compat layers (e.g. in clisp,
oaklisp, Franz Lisp).
It used to instruct the kernel about paging policy (G/C aware, flush etc).
Newly compiled code (assuming that it will detect vadvise()) will use the
libc stub for vadvise(). The headers for this interface are gone.
vadvise(2) could be marked as COMPAT_80, but as long as we support ultrix,
sunos or aout68k ABI, don't bother with this.

drive instead of its associated vfsops. Makes it more friendly, and allows
compat binaries to autoload VFS modules if needed.

their content into "itp". There's no need for re-reading the whole binary and
trying to find this section again. Just use "itp".
DEBUG_FREEBSD_ELF is now unused, so remove its references in amd64/conf/ALL
and i386/conf/ALL.
to store disk quota usage and limits, integrated with ffs
metadata. Usage is checked by fsck_ffs (no more quotacheck)
and is covered by the WAPBL journal. Enabled with kernel
option QUOTA2 (added where QUOTA was enabled in kernel config files),
turned on with tunefs(8) on a per-filesystem
basis. mount_mfs(8) can also turn quotas on.

for details.
- update the linux syscall table for each platform.
- support new-style (NPTL) linux pthreads on all platforms.
clone() with CLONE_THREAD uses 1 process with many LWPs
instead of separate processes.
- move the contents of sys__lwp_setprivate() into a new
lwp_setprivate() and use that everywhere.
- update linux_release[] and linux32_release[] to "2.6.18".
- adjust placement of emul fork/exec/exit hooks as needed
and adjust other emul code to match.
- convert all struct emul definitions to use named initializers.
- change the pid allocator to allow multiple pids to refer to the same proc.
- remove a few fields from struct proc that are no longer needed.
- disable the non-functional "vdso" code in linux32/amd64,
glibc works fine without it.
- fix a race in the futex code where we could miss a wakeup after
a requeue operation.
- redo futex locking to be a little more efficient.
and nfssvc unsupport unconditional. nfs server was just a fancy
NOP anyway for all except Ultrix. I know I'm boring but I couldn't
imagine why someone would want to run an Ultrix nfs server (and I
also doubt that it would work anymore with all the changes to fs
exporting etc).
anyone wanting to run lfs megamaid as a e.g. FreeBSD binary.
Besides, the real action has been in fcntl() for >5 years now.
The only place where the compat syscalls might have made the tiniest
bit of sense was netbsd32, but they were unimplemented there.
