The branch stable/13 has been updated by dchagin: URL: https://cgit.FreeBSD.org/src/commit/?id=fbed3bdfd4ca06459590ad2b713a8b6eea53e832 commit fbed3bdfd4ca06459590ad2b713a8b6eea53e832 Author: Dmitry Chagin <dchagin@FreeBSD.org> AuthorDate: 2022-06-17 19:33:04 +0000 Commit: Dmitry Chagin <dchagin@FreeBSD.org> CommitDate: 2022-06-17 19:33:04 +0000 Call sv_onexec hook after the process VA is created. For future use in the Linux emulation layer call sv_onexec hook right after the new process address space is created. It's safe, as sv_onexec used only by Linux abi and linux_on_exec() does not depend on a state of process VA.
