https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=203891 crest@rlwinm.de changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |crest@rlwinm.de --- Comment #2 from crest@rlwinm.de --- While not exactly what you're asking for FreeBSD does offer aio_fsync(2) to implement asynchronous file syncing. In theory this offers the kernel the opportunity to flush data to stable storage at the optimal pace and notify the application about it. If we're talking about OS specific code paths its also possible to receive the notification via kqueue(2) + kevent(2) instead of polling or signals. Too bad that the kernel requires that much babysitting from userland. -- You are receiving this mail because: You are the assignee for the bug.
