The branch main has been updated by brooks: URL: https://cgit.FreeBSD.org/src/commit/?id=ef9871c6205c158b16ee23702d2b8c043debc51a commit ef9871c6205c158b16ee23702d2b8c043debc51a Author: Brooks Davis <brooks@FreeBSD.org> AuthorDate: 2024-01-17 20:26:52 +0000 Commit: Brooks Davis <brooks@FreeBSD.org> CommitDate: 2024-02-05 20:34:56 +0000 libthr: move _umtx_op_err() to libsys Declare in sys/umtx.h and implement in libsys. Explicitly link libthr with libsys. When building libthr static include _umtx_op_err so we don't break static linkage with -lpthread.
