While working on adding syncfs() support in FUSE, I've hit some severe bugs with submounts (a crash and an infinite loop). The fix for the crash is straightforward (patch 1), but the fix for the infinite loop is more invasive : as suggested by Miklos, a simple bug fix is applied first (patch 2) and the final fix (patch 3) is applied on top.
