But from user's perspective, they open a file with O_RDWR, get a success, then write returns EROFS? Besides, EXT3 ALWAYS return EROFS for the 1st and 2nd case, even you specify errors=continue, things are still the same. regards, ---- Qu Fuping - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
