[PATCH 15/32] Unionfs: implement f/async

From: Erez Zadok <[EMAIL PROTECTED]> Unionfs needs its own fsync and fasync instead of calling the generic file_fsync, because it may have to sync multiple writable lower branches (not just one). This also allows Unionfs to compile with CONFIG_BLOCK=n. Signed-off-by: Erez Zadok <[EMAIL
