syncthing: Enable inotify on x86_64#174
Merged

Conversation
Upstream Syncthing currently disables inotify on Android x86_64 because it uses golang.org/x/sys's unix.EpollWait function, which is implemented in terms of epoll_wait on x86_64. That syscall is blocked by Android's x86_64 seccomp policy. I've reported this at golang/go#80080, but in the meantime, we can temporarily fork the golang.org/x/sys package to make it use epoll_pwait (same as what bionic libc does) on x86_64. This allow file watchers to work in the Android emulator. Signed-off-by: Andrew Gunnerson <accounts+github@chiller3.com>
