Miklos Szeredi cdb6727958 ovl: lookup whiteouts outside iterate_dir() ... If jffs2 can deadlock on overlayfs readdir because it takes the same lock on ->iterate() as in ->lookup(). Fix by moving whiteout checking outside iterate_dir(). Optimized by collecting potential whiteouts (DT_CHR) in a temporary list and if non-empty iterating throug these and checking for a 0/0 chardev.
