I don't quite agree with this. It seems that there is still a long way to go to solve the problem of namespaces, and the issues here are more urgent. |
- organize handle_syscall - add (un)link - add geteuid, get(e)gid - add warning for pipe2

Content
arceos_posix_apiand integrate the code here.bindgengenerated type with linux_raw_sys.UserPtrrelated stuffs.

getdents64has issues but I actually don't know how to fix it. I'm asking @eternalcomet to make a PR maybe.Since we no longer definetimespec,timevalorsockaddrourselves but using the definition from linux_raw_sys, we can't implement conversion traits (From<Duration>and etc) on it. So a set of conversion functions are added.FilePathis still ugly but I don't touch it. I'm hoping of path types fromaxfs-ng-vfs.
