Subject: tools/nolibc/sys: make getpgrp(), getpid(), gettid() not set errno
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=830acd088edc1604ee46916188491ef634441fc6;p=linux.git

tools/nolibc/sys: make getpgrp(), getpid(), gettid() not set errno

These syscalls never fail so there is no need to extract and set errno
for them.
