https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=220459 Bug ID: 220459 Summary: lio_listio(2) doesn't support SIGEV_THREAD Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: asomers@FreeBSD.org lio_listio(2) returns EINVAL when its sig->sigev_notify is SIGEV_THREAD. That error gets returned from kern_lio_listio. The lio_listio(2) man page makes no mention of this limitation. In fact, it says that SIGEV_THREAD _is_ supported. For other aio(4) functions, SIGEV_THREAD is handled in librt and implemented using SIGEV_THREAD_ID, which is what the kernel actually sees. But lio_listio doesn't go through librt. Instead, it's a direct syscall. Either the man page should be updated, or lio_listio should gain a librt wrapper just like aio_read(2) and friends. -- You are receiving this mail because: You are the assignee for the bug.
