The branch main has been updated by dchagin: URL: https://cgit.FreeBSD.org/src/commit/?id=c30a767c6fd6d3f19e897fb800513e75175249b9 commit c30a767c6fd6d3f19e897fb800513e75175249b9 Author: Dmitry Chagin <dchagin@FreeBSD.org> AuthorDate: 2022-05-30 16:49:45 +0000 Commit: Dmitry Chagin <dchagin@FreeBSD.org> CommitDate: 2022-05-30 16:49:45 +0000 linux(4): Microoptimize rt_sendsig(), convert signal mask once On amd64 Linux saves the thread signal mask in both contexts, in the machine dependent and in the machine independent. Both contexts are user accessible. Convert the mask once, then copy it.
