The branch main has been updated by trasz: URL: https://cgit.FreeBSD.org/src/commit/?id=0dfbdd9fc269f0438ffcc31632d35234a90584ad commit 0dfbdd9fc269f0438ffcc31632d35234a90584ad Author: Edward Tomasz Napierala <trasz@FreeBSD.org> AuthorDate: 2021-03-12 15:31:37 +0000 Commit: Edward Tomasz Napierala <trasz@FreeBSD.org> CommitDate: 2021-03-12 15:31:45 +0000 linux(4): make getcwd(2) return ERANGE instead of ENOMEM For native FreeBSD binaries, the return value from __getcwd(2) doesn't really matter, as the libc wrapper takes over and returns the proper errno.
