From: Sergiu Moga Date: Mon, 24 Mar 2025 16:58:57 +0000 (+0200) Subject: lib/posix-process: Fix `vfork` signature X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=ae4cef9a9a3ae16a470fd0bc800f0ad2b3f7d0d3;p=unikraft%2Funikraft.git lib/posix-process: Fix `vfork` signature A minor oversight during merging of the `vfork` functionality ended up defining `vfork` with an invalid signature that takes two arguments. Fix this by defining `vfork` as a syscall that takes no arguments.
