hujianyang 2f83fd8c28 ovl: Fix kernel panic while mounting overlayfs ... The function ovl_fill_super() in recently multi-layer support version will incorrectly return 0 at error handling path and then cause kernel panic. This failure can be reproduced by mounting a overlayfs with upperdir and workdir in different mounts. And also, If the memory allocation of *lower_mnt* fail, this function may return an zero either. This patch fix this problem by setting *err* to proper error number before jumping to error handling path.
