Could we rename __syscall_return to IS_SYS_ERR (or whatever) and force
kernel syscall users to do the check? That way we could eliminate errno

s/users/user/ .. there's one left that should die out soon ;)

Only one in unistd.h, but throughout the kernel there are quite a few
unless I'm missing something here:
doener@atjola:~/src/kernel/linux-2.6$ grep \ _syscall * -R | \

grep -v define\\\|undef\\\|clobber | wc -l

116

Are these just going to be replaced by calls to sys_whatever?

they're not the users of this, they're the definitions... ;)

Well, I assume that if some code defines a syscall, it will actually use
it. Of course I meant to ask if the users of those definitions are going
to just call sys_whatever.
For example check_host_supports_tls in arch/um/os-Linux/sys-i386/tls.c
which even uses the global errno (although in that case the whole
else part could probably be just removed).
